CVE-2026-106173 is a critical (CVSS 9.4) unauthenticated arbitrary file write in FortiSIEM's phQueryMaster gRPC service on port 27918/TCP. The SendQueryResult method builds a path from the query-id parameter without validation, so "../" sequences escape the directory and a null byte drops the appended filename and extension. Overwriting /opt/charting/redishb.sh, which runs every 60 seconds, gives remote command execution. Horizon3.ai published the analysis and a PoC.

Rapid7 emergency-response analysis of CVE-2026-104935, a CVSS 8.6 authentication bypass by spoofing (CWE-290) in Ivanti Connect Secure that allows unauthenticated remote command execution. It was exploited as a zero-day against a limited number of customers, added to CISA KEV on disclosure day, and Volexity observed it chained with a still-unpatched privilege escalation flaw. Part of the fix shipped in 25.1.3.0 in July 2026, with backports to other supported versions pending. Rapid7 advises emergency patching outside normal cycles and hunting for compromise using Volexity's IOCs, since Ivanti has no reliable ones.

CVE-2026-57860 describes an arbitrary code execution flaw in ForgeCode (tailcallhq/forgecode), an AI pair-programming CLI that automatically loads and executes MCP servers defined in a repository's .mcp.json on startup without user confirmation. A malicious repo can define mcpServers entries with arbitrary command/args (e.g. bash -c) that spawn under the invoking user's privileges the moment forge is run inside the cloned repo, giving attackers a reliable initial-access and persistence primitive against developers evaluating untrusted code. CVSS 4.0 8.4 HIGH, CWE-829 (inclusion of functionality from untrusted control sphere); a fix commit and VulnCheck advisory are linked.

CVE-2026-16584 affects AWS API MCP Server (awslabs.aws-api-mcp-server) versions 0.2.13 through 1.3.46: if the security policy enforcement data fails to initialize at server startup, the tool silently skips policy checks for the rest of the process's life, letting an agent execute AWS API operations the admin configured the policy to deny or gate. Underlying IAM permissions still apply and are unaffected, but the intended allow/deny gating layer is bypassed (CWE-455, improper handling of initialization failure). Fixed in 1.3.47.

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.

The Solidity team discloses a bug (reported by Cantina Security via the Ethereum Foundation bug bounty) where the IR-based (--via-ir) code generator pushed named custom-error arguments in call-site order instead of declaration order before ABI-encoding, corrupting revert data for require(condition, ErrorName({...})) calls with reordered named parameters. 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.

Socket details a compromise of @injectivelabs/sdk-ts version 1.20.21 (a popular Injective Labs TypeScript SDK with ~50,000 weekly downloads), in which the fromMnemonic and fromHex key-derivation functions were hooked with a trackKeyDerivation call that base64-encodes and exfiltrates wallet private keys and mnemonic phrases to a lookalike Injective public infrastructure endpoint. The attacker gained access via a legitimate maintainer's GitHub account, published the malicious version, and simultaneously pushed version 1.20.21 to 17 other @injectivelabs-scoped packages pinned to the compromised SDK, amplifying blast radius to transitive dependents. The compromise was detected and reverted within roughly an hour by the account owner, but the malicious release artifacts remained downloadable on npm and GitHub at time of writing.

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.

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.
