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.

Tenable disclosed it after failed vendor contact, VulnCheck has confirmed active exploitation against roughly 7,000 internet-exposed instances, and a public PoC exists; fixed in Langflow 1.9.0/1.10.0 and langflow-base 0.8.3.

Orca Security details CVE-2026-45034 (CVSS 9.8), a bypass of PhpSpreadsheet's File::prohibitWrappers() protection that was originally added to fix CVE-2026-34084. A crafted path with three or more slashes after the scheme (e.g. phar:///path/exploit.phar/dummy.csv) causes PHP's parse_url() to return false instead of a scheme string, skipping the is_string($scheme) check while PHP's stream layer still treats the path as a phar wrapper, enabling automatic phar deserialization via IOFactory::load() and full RCE on PHP 7.x (file-read primitive on PHP 8.x, with RCE restored if Phar::getMetadata() is later called). All 1.x versions through 1.30.4 are affected; PhpSpreadsheet 1.30.5 patches the issue, and the post recommends replacing parse_url()-based checks with str_contains($filename, '://') validation.

Aikido Security discovered an unauthenticated authentication bypass in phpBB (versions up to 3.3.16 and 4.0.0-a2) that lets an attacker forge a valid session for any user via a single HTTP request, since the member list is public by default. Admin account takeover exposes full read/write/delete access, though a separate ACP password check blocks direct RCE. Fixed in phpBB 3.3.17, disclosed via HackerOne with a 4-day patch turnaround; technical exploit details withheld pending upgrade adoption.

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 CVE-2026-0300, a CVSS 9.3 buffer overflow in PAN-OS's User-ID Authentication Portal (Captive Portal, ports 6081/6082) that lets unauthenticated attackers trigger an out-of-bounds write and achieve remote code execution with root privileges. 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-2026-23744 describes an unauthenticated remote code execution vulnerability in MCPJam Inspector (versions ≤1.4.2), a debugging/testing tool for MCP servers. The tool's HTTP server binds to 0.0.0.0 by default and exposes a server-management endpoint with no authentication, letting any network-adjacent (or internet-facing) attacker install a malicious MCP server and execute arbitrary code on the developer's host with no user interaction, CVSS 9.8. Fixed in v1.4.3, which restricts the bind address and adds endpoint authentication.

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.
