Rapid7 analysis of CVE-2026-97229, a CVSS 10.0 integer overflow (CWE-190) in the Onigmo regex compiler used by GitLab CE/EE's CI/CD regex handling. A crafted regex in a .gitlab-ci.yml passes validation as US-ASCII, then is recompiled for a UTF-8 repository path, producing invalid instructions that give code execution as the git user. Rapid7 reproduced it on GitLab CE 19.4.1 with ASLR (patched in 19.4.2); despite the vendor's "unauthenticated" rating, the attacker needs to commit a malicious config to a public project, which self-registration allows. No in-the-wild exploitation is confirmed, and Rapid7 recommends urgent upgrades.

Rootshell Security Bulletin #22 (Aug 1998) reports an ICQ authentication flaw found by a Linux ICQ clone developer. The Mirabilis server stores 8-character passwords, and sending a password of 9 or more characters (e.g. "123456789") overflows the buffer and logs the client in as any UIN not already online. This gives full account takeover, including receiving offline messages. It is not spoofing, and it works with unofficial clients such as zicq, since the official client enforces the length limit client-side.

A GitHub Security Advisory (GHSA-5p9g-j988-pcwv) documents a session poisoning flaw in the Ruby MCP SDK's Streamable/SSE HTTP transport: the server never validates that a POST to /messages/{session_id} actually belongs to the caller, so an attacker who obtains a victim's session ID (e.g. via logs or network sniffing) can silently execute tool calls whose responses are delivered into the victim's own SSE stream. The advisory includes a working PoC (attacker/legitimate client scripts against the SDK's example streamable_http_server.rb), notes that csharp-sdk and go-sdk correctly bind sessions to user identity while ruby-sdk does not, and distinguishes the bug from the related "Stream Replacement" advisory (GHSA-qvqr-5cv7-wh35), which disconnects rather than poisons the victim's stream.

GHSA advisory for jovancoding/network-ai disclosing that its MCP HTTP transport (bin/mcp-server.ts, lib/mcp-transport-sse.ts) accepts JSON-RPC tools/call requests with zero authentication, session, or origin checks, and binds to 0.0.0.0 by default. The PoC shows an unauthenticated attacker can enumerate 22 registered tools and invoke privileged ones - config_get/config_set to read and mutate live orchestrator configuration, agent_list/agent_spawn/agent_stop, token_create/token_revoke, budget_set_ceiling, and blackboard_write/delete - with curl requests against a local Docker deployment. Remediation recommended enforcing bearer-token auth in _handlePost() before dispatch, defaulting to 127.0.0.1 binding, and gating state-mutating tools behind authorization checks.

GHSA-9hgc-g3w5-67cm details a DNS TOCTOU race in IBM mcp-context-forge's /admin/gateways/test endpoint: validate_gateway_test_url() resolves and vets a hostname against private/cloud-metadata IP ranges, but the actual request is made with httpx (via ResilientHttpClient), which independently re-resolves DNS at connection time with no IP pinning. An attacker with gateways.read permission can exploit DNS rebinding (short-TTL record flipping from a public IP to 169.254.169.254) to bypass SSRF protections and reach cloud instance metadata, exfiltrating IAM credentials where IMDSv1 is enabled. The advisory notes the codebase already acknowledges the gap in two comments and a tracked TODO (ICACF-15), and recommends pinning the validated IP into the connection.

GHSA advisory detailing three bypasses in Flowise's Custom MCP Server security controls (validateCommandFlags and validateArgsForLocalFileAccess in packages/components/nodes/tools/MCP/core.ts) that combine to achieve remote code execution: an unblocked `docker build` subcommand that pulls and runs a remote Dockerfile, a missing `--yes` long-flag alias on the npx blocklist (only `-y` was blocked) enabling arbitrary npm package execution, and a Unix absolute-path regex that fails to catch double-leading-slash paths (`//root/...`), allowing `node` to execute an uploaded local file.

CISA added seven vulnerabilities to its Known Exploited Vulnerabilities Catalog on the basis of active exploitation. They are SQL injection in Sangoma Switchvox, HTTP request/response smuggling in Kludex Starlette, OS command injection in Kestra OSS, improper authentication in BerriAI LiteLLM and JFrog Artifactory, and SSRF plus OS command injection in SonicWall SMA1000 appliances. The alert restates BOD 26-04, which makes federal agencies prioritise rapid remediation of KEV CVEs on publicly exposed assets that grant total control after exploitation. It also requires agencies to check for prior compromise before patching.

Belgian CCB advisory on CVE-2026-48710 ("BadHost", CVSS 6.5), an authentication bypass in Starlette versions before 1.0.1. The Host header was not validated when request.url was rebuilt, so request.url.path could differ from the routed path. Middleware and endpoints that enforce access control on request.url could therefore be bypassed. The flaw affects FastAPI, LiteLLM, vLLM, MCP servers and other Python LLM infrastructure, and may expose stored third-party credentials. The advisory recommends upgrading to 1.0.1 or later and increasing monitoring, and links to the badhost.org scanner and to the GitHub, OSTIF, X41 D-Sec and Ars Technica write-ups.

Flashbots disclosed a critical storage-aliasing vulnerability in V1 of the Priority Update Registry (PUR), an on-chain price feed contract used by trading integrators like propAMMs. Because lane storage slots were computed as keccak256(target, unbounded caller-controlled index) while the updater-authorization mapping lived at slot 0 with the same keccak256 shape, any caller could craft a lane index that collided with isUpdater[target][attacker], letting them self-authorize as an updater and publish arbitrary prices or deauthorize legitimate updaters. The fix namespaces the lane slot derivation (keccak256(NAMESPACE, target, laneIndex)) to make the preimages structurally non-collidable, and the advisory gives integrators concrete migration guidance since authorizations and lane state must be re-established on the new deployment.

The Solidity team disclosed a code-generator bug (reported by Shaheen Fazim via the Ethereum Foundation bug bounty program) where `delete b[i]` on a bytes/string element located in memory incorrectly writes a full 32-byte zero word instead of a single byte, corrupting up to 31 subsequent bytes — either later elements of the same array or, for elements near the array's end, adjacent memory allocations like other variables. The bug affects only the default evmasm pipeline (not the IR pipeline via --via-ir) in all versions up to and including 0.8.36, is fixed in 0.8.37, and the equivalent assignment `b[i] = 0` is unaffected and serves as a workaround.

The bug requires --via-ir compilation plus a narrow set of conditions (mutual recursion, >16 live locals in reachable non-recursive functions, a variable read back after the recursive call) and affects Solidity 0.7.2 through 0.8.36; a rescan of ~319,000 Sourcify-verified contracts found no affected deployments.

Introduced in Solidity 0.8.26 and fixed in 0.8.37, the bug produces silently swapped or type-confused values in decoded revert data with no compiler warning, and can cause misaligned encoding in multi-slot-argument cases that either reverts with undecodable data or produces a plausible-but-wrong payload - a real concern for standards like ERC-3668 (CCIP Read) that treat revert data as part of the contract interface. Severity was rated "very low" since the affected transaction is already reverting and there is no attacker-controlled exploitation path, but audits of via-ir contracts using named custom-error arguments should check for it.

Endor Labs researchers found a critical type confusion vulnerability (GHSA-864f-rcv7-6rh4) in isolated-vm, the Node.js library used to run untrusted JavaScript inside a separate V8 Isolate. A TOCTOU bug in ExternalCopy's transferList handling — where a malicious getter returns a valid ArrayBuffer on a validating pass but an attacker-controlled value on the unchecked second pass — lets guest code escalate from a controlled-address crash to full host control-flow hijack, given only a single ivm.Reference. The bug is fixed in isolated-vm 7.0.1/6.2.0; affected downstream users include n8n, Activepieces, Mastra, Budibase, Sim.ai, Directus, and Rocket.Chat, which rely on isolated-vm to sandbox user- and model-generated code.

This GHSA advisory documents CVE-2026-27826, a DNS-rebinding TOCTOU bypass of the SSRF fix in the MCP Atlassian server (mcp-atlassian PyPI package). The prior patch (GHSA-7r34-79r5-rcc9) added validate_url_for_ssrf, which resolves the attacker-controlled X-Atlassian-{Jira,Confluence}-Url header host once at middleware time but discards the resolved IP; the actual outbound request later re-resolves the raw hostname at connect time with no IP pinning, so a rebinding DNS name can pass validation with a public IP and then connect to 169.254.169.254 or an internal address, restoring unauthenticated SSRF to cloud metadata/internal services even on the 'patched' build. The advisory includes an executed PoC against the real urls.py, exact code locations (utils/urls.py, servers/main.py, servers/dependencies.py), and remediation via a custom resolver/cached-getaddrinfo adapter to pin the validated IP.

Solidity 0.8.36 release notes disclose two medium-severity compiler bugs: a Yul optimizer call-cycle detection flaw that let stack-to-memory spilling be wrongly applied to mutually recursive functions, causing separate invocations to share and overwrite the same memory slots; and a storage-layout warning bug that could reverse the AST's linearizedBaseContracts annotation when a contract's variables sit very close to the end of storage, corrupting constructor/state-variable initialization order. The release also adds experimental stack-to-memory spilling to the new SSA-form CFG code generator (behind --experimental --via-ssa-cfg) and removes the now-obsolete experimental EOF backend after EOF's rejection from the Fusaka upgrade.

The Solidity team discloses a medium-severity compiler bug present from Solidity 0.8.29 through 0.8.35 (fixed in 0.8.36): the code that emits Warning 3495 (custom storage layout too close to storage end) uses ranges-v3's actions::reverse instead of views::reverse, permanently mutating the linearizedBaseContracts AST annotation instead of only reading a reversed copy. Because that annotation drives inheritance-order decisions throughout analysis and codegen, affected contracts can get reversed constructor execution order, wrong super/virtual-function and virtual-modifier resolution, and incorrect fallback/receive dispatch — either silently miscompiling or triggering internal compiler errors. Exploitation requires a contract using both inheritance and a `layout at` clause landing within the last 2^64 storage slots, a pattern the team found no real-world evidence of via GitHub and Sourcify scans.

The verifier blocks the literal reserved token "telegram" but not path separators, so a token like "../fast-mcp-telegram/telegram" lets a remote HTTP client authenticate as the default legacy session, bypassing the control meant to keep multi-user HTTP sessions from colliding with the default stdio/legacy account.

The bug lives in handle_forgot_password() of the CompLibFormHandler class, whose custom REST endpoint accepts an attacker-supplied email instead of the account registered address, letting an attacker redirect the password-reset link and seize admin accounts. Active exploitation is already confirmed (Wordfence logged 59 blocked attacks in 24 hours), and roughly 150,000 of 500,000+ installs remain unpatched pending the 6.0.7 fix.

Orca Security details CVE-2026-45618, a CVSS 10.0 unauthenticated RCE in LiquidJS (Shopify's Liquid template engine for Node.js, 7.3M+ monthly npm downloads) affecting all versions prior to 10.26.0. Attackers craft a template expression using the valueOf filter (1|valueOf) to escape the sandbox, chain prototype manipulation to reach internal engine objects (parser, loader, filters), and ultimately invoke the JavaScript Function constructor for arbitrary command execution; a public PoC demonstrates file reads and execSync-based RCE, and CCB Belgium's national CERT has issued an advisory urging immediate patching.

Orca Security breaks down CVE-2026-45695 (CVSS 9.8), an unauthenticated RCE in the Kopia backup tool's HTTP server, affecting versions 0.22.3 and earlier. The flaw stems from Kopia's /api/v1/repo/exists endpoint splitting SFTP storage configuration fields on literal spaces without a proper tokenizer or quote handling, letting an attacker inject `-oProxyCommand=<cmd>` into the SSH command line when the server runs with --without-password and SFTP/external-SSH enabled — achieving code execution via a single crafted HTTP request. Fix is Kopia 0.23.0, which blocks starting with --insecure/--without-password on non-loopback interfaces; researcher Daniele Berardinelli reported it, tracked as GHSA-2q4c-3mrw-63c3.

Orca analysis of CVE-2026-46354 (CVSS 9.1) in the Coder remote development platform. azureidentity.Validate() checks that the PKCS#7 signer certificate chains to a trusted Azure CA but never verifies the signature on the envelope. An unauthenticated attacker can send a forged envelope, using a public Azure IMDS certificate and a known vmId, to POST /api/v2/workspaceagents/azure-instance-identity. This yields workspace agent session tokens, and through them Git SSH keys and OAuth tokens. The post lists the affected v2 and v1 versions, the patched releases (v2.33.3, v2.32.2, v2.31.12, v2.30.8, v2.29.13, v2.24.5) and the workaround of disabling Azure instance identity auth. Coder v1 has no patch.

CVE-2026-45829 (CVSS 10.0) is a pre-authentication remote code execution flaw in ChromaDB's Python FastAPI server, versions 1.0.0 through 1.5.8. The server processes user-controlled embedding function configuration before authentication checks, letting an attacker send a crafted collection-creation request referencing a malicious HuggingFace model with trust_remote_code enabled to force arbitrary Python code execution pre-auth. Discovered by researcher Azraelxuemo and later HiddenLayer (dubbed "ChromaToast Served Pre-Auth"); Shodan-based scanning found roughly 73% of internet-exposed ChromaDB instances still vulnerable, with fixes shipped in 1.5.9.

Orca Security breaks down CVE-2026-9082, a critical unauthenticated SQL injection in Drupal core's database abstraction API affecting PostgreSQL-backed sites running versions 8.9.0 through 11.3.9. The flaw stems from insufficient query sanitization and can lead to full data exposure, privilege escalation, and in some configurations remote code execution; Drupal has shipped patched releases (e.g. 11.3.10, 10.6.9) and MySQL/MariaDB sites are unaffected by the SQLi itself but should still update for bundled Symfony/Twig fixes.

Packagist disclosed that Composer versions prior to 2.9.8, 2.2.28 LTS, and 1.10.28 could leak full GitHub Actions GITHUB_TOKEN and GitHub App installation token values into CI logs when a token failed Composer's outdated validation regex, triggered by GitHub's since-rolled-back rollout of a new hyphenated token format. Common setups like shivammathur/setup-php that auto-register GITHUB_TOKEN into Composer's global auth.json are called out as at risk, and teams are urged to update Composer immediately and audit Actions logs for exposed credentials.

Wiz analyzes Fragnesia, a Linux kernel local privilege escalation in the XFRM ESP-in-TCP subsystem and a new variant of the Dirty Frag family, introduced as a side effect of a Dirty Frag patch. File-backed pages spliced into a TCP receive queue before the socket switches to espintcp ULP mode are decrypted in place, so AES-GCM keystream manipulation gives deterministic single-byte page-cache writes. The PoC uses user and network namespaces for CAP_NET_ADMIN, installs an ESP security association via NETLINK_XFRM, and overwrites /usr/bin/su in page cache to get a root shell. Ubuntu's AppArmor restrictions on unprivileged user namespaces partially mitigate it, and the post recommends vendor patches and disabling the vulnerable modules.

GitHub changelog entry announcing two repository ruleset changes. Individual users can now be added as bypass actors on repository-level rulesets through the UI, REST API and GraphQL, so a dedicated team or role is no longer needed for a single person or service account. Repository admins can also rename a branch covered by an organization or enterprise ruleset, but only if the new name stays within the scope of every ruleset that applied to the old one. Otherwise the rename is blocked and an org or enterprise admin must do it, and org and enterprise admins can turn the capability off. This matters for branch-protection governance because bypass lists and rename rights affect who can circumvent required controls.

Orca Security's write-up of CVE-2026-23918 (CVSS 8.8), a double-free memory corruption bug in Apache HTTP Server's mod_http2 stream cleanup logic. An unauthenticated attacker can trigger it by sending crafted HTTP/2 HEADERS frames followed by an early RST_STREAM with a non-zero error code. This causes heap corruption, crashes, and possibly remote code execution. Version 2.4.66 is affected and 2.4.67 fixes it. Public PoC details exist, but no in-the-wild exploitation had been reported. Disabling HTTP/2 is given as a temporary workaround.

Socket disclosed that a critical sandbox escape in vm2 (GHSA-ffh4-j6h5-pg66, CVE-2026-26956), which lets attacker-controlled JavaScript passed to VM.run() escape isolation and execute arbitrary OS commands via WebAssembly.JSTag, affects far more than the officially listed vm2 3.10.4/Node 25 scope. Socket's testing showed 66 vm2 releases from 0.2.2 through 3.10.4 are exploitable on Node.js 24.15.0, and any Node runtime exposing WebAssembly.JSTag is vulnerable, meaning downstream SCA/scanner tools using the narrower advisory data would miss real exposure. Socket is releasing free Certified Patches (via `socket patch add`) for the issue alongside upgrade guidance to vm2 3.10.5+.

Wiz details "Dirty Frag" (CVE-2026-43284 and CVE-2026-43500), a Linux kernel local privilege escalation chain combining page-cache write primitives in the xfrm-ESP (IPsec) and RxRPC subsystems that let an unprivileged-but-CAP_NET_ADMIN attacker corrupt page-cache-backed memory to gain root. It is a deterministic (non-race-condition) bug class similar to Dirty Pipe and is a successor to the earlier Copy Fail (CVE-2026-31431); a public PoC exists but no official patch is available yet, and affected code paths date back to 2017 (ESP) and 2023 (RxRPC).

Palo Alto Networks has confirmed limited in-the-wild exploitation against internet-exposed instances; Wiz reports 7% of environments have publicly exposed PAN-OS and Shodan shows 67 exposed servers on port 6081. Guidance includes patching once fixes ship, restricting the Authentication Portal to trusted networks, and disabling it if unused.

Wiz's analysis of CVE-2026-31431 ("Copy Fail"), a logic flaw in the Linux kernel's AEAD crypto implementation (algif_aead) that, when chained with AF_ALG sockets and splice(), lets an unprivileged local user write 4 controlled bytes into the page cache of any readable file — including setuid binaries like /usr/bin/su — to gain root. It affects nearly all kernels built since 2017, also enables container escape between co-located containers sharing a base image, and the post covers patch status, seccomp-based mitigation, and detection heuristics (delayed AF_ALG loading, malformed su auth.log entries).

Analysis of CVE-2025-62878 (CVSS 10.0), a path traversal flaw in Rancher's Local Path Provisioner — the default StorageClass backend for K3s — caused by unsanitized pathPattern templates in StorageClass definitions being joined into filesystem paths via filepath.Join. Exploitation lets an attacker escape the configured base storage directory to read/write/delete arbitrary host files (e.g. /etc/kubernetes/pki, /root/.ssh/authorized_keys) through a helper pod that gains host access via a hostPath mount rather than privileged mode, evading policies that only block privileged containers. The piece also challenges the CVSS 10.0 rating given the cluster-admin RBAC typically required, and covers a post-patch bypass via the allowUnsafePathPattern escape hatch.

CVE-2026-25536 is a cross-client data leak in the official MCP TypeScript SDK (v1.10.0-1.25.3, CVSS 7.1): when a single McpServer instance reuses a StreamableHTTPServerTransport across multiple concurrent client connections, a race condition in the response multiplexing logic can route one client's tool results, resource content, or errors to a different client. This breaks tenant isolation in multi-user MCP server deployments, a common production pattern, potentially exposing sensitive API responses, file contents, or database query results across security boundaries. Fixed in SDK v1.26.0; recommended mitigations include upgrading, using per-client McpServer instances, and adding client-side response correlation checks.

CVE-2026-21852 describes a flaw in Claude Code versions prior to 2.0.65 where a malicious repository's settings file can override ANTHROPIC_BASE_URL and have it applied during project load before the user sees or accepts the trust-confirmation prompt, causing the user's Anthropic API key to be sent to an attacker-controlled endpoint. The root cause is an initialization-order bug (CWE-522, insufficiently protected credentials) where untrusted repo config is parsed and acted on ahead of trust verification; Anthropic fixed it in 2.0.65 by moving trust checks before config processing. Mitigations include updating, rotating exposed keys, and avoiding opening unfamiliar repos until patched.

Huntress reverse-engineered Gladinet CentreStack/Triofox's filesvr.dn HTTP handler and found that its AES-256 "Access Ticket" encryption uses hardcoded, static key/IV strings (Chinese and Japanese marketing text embedded in GladCtrl64.dll) extracted from the SysKeyMgr class, assigned CVE-2025-14611 (CVSS 7.1). Because the keys never change, attackers can forge tickets with arbitrary timestamps to read the server's web.config and steal ASP.NET machine keys, enabling ViewState deserialization RCE; this was chained with a prior auth bypass (CVE-2025-11371) and observed exploited in the wild against at least nine organizations. Later updates report suspected cl0p ransomware group exploitation of CVE-2025-30406 (ViewState deserialization) against internet-facing CentreStack servers, with IOCs including a "conqueror.exe" payload and specific attacker IPs.

Writeup of CVE-2024-50306, a vulnerability in Apache Traffic Server (versions 9.0.0-9.2.5 and 10.0.0-10.0.1) where the code fails to check the return value of initgroups() when dropping privileges after startup. If the call fails, the process believes it has dropped supplementary group memberships when it has not, potentially leaving it in a privileged group and enabling privilege escalation. Fixed in ATS 9.2.6/10.0.2 by aborting execution on failure.

Researcher writeup on CVE-2023-47480, where the Pure Data (Pd) visual programming language failed to check return values of set*id() family functions (e.g. setuid()), which could allow the process to silently continue running with elevated privileges if the privilege-drop call failed. Maintainers (fixed by Umläute) patched it in Nov 2023 to abort execution on setuid() failure; the author notes this is the same bug class as their earlier CVE-2023-40303 in GNU inetutils. Impact is rated moderate since triggering setuid() failure is hard and Pd is not widely deployed.

Because privilege-dropping calls are not verified, failure conditions can leave a process running with unintended elevated privileges, enabling local or in some server-daemon cases remote privilege escalation; the fix landed in the inetutils master branch ahead of a future release.

Writeup by the researcher who reported CVE-2023-38336, a command injection vulnerability in Netkit's rcp implementation (Debian's rsh-client package). The bug is in susystem() in rcp/rcp.c, which passes filename arguments unsanitized to `sh -c`, letting an attacker who controls a copied filename execute arbitrary commands (demonstrated via `ltrace` with a filename like `";whoami"`); the binary is SUID root but drops privileges via setuid() before executing the shell, so the flaw grants command execution as the invoking user rather than root escalation. No patch exists since the project has no upstream maintainer, and the author recommends migrating from RSH to SSH.
