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.

Alert summarizing Socket Threat Research's disclosure that a malicious version of the Tensorlake npm SDK (an AI-agent infrastructure package) was published with a preinstall hook delivering Shai-Hulud/ChainDrop credential-stealing malware. The payload targets GitHub, npm, AWS, Kubernetes and Vault credentials, persists via a gh-token-monitor mechanism, and spreads through compromised publishing accounts. It lists IOCs (lib/setup.mjs, lib/Math_Symbol.js) and warns to remove the persistence before revoking stolen GitHub tokens, since revocation triggers a destructive routine. Socket detected the release about 11 minutes after publication.

Endor Labs documents the compromise of tensorlake@0.5.144, the official npm TypeScript SDK for Tensorlake, which shipped a Shai-Hulud worm payload via a poisoned preinstall hook (node lib/setup.mjs) after the project's main branch was altered and pushed through a legitimate, provenance-signed GitHub Actions release pipeline. The malware harvests npm, GitHub, SSH, cloud (AWS/GCP/Azure), Kubernetes/Docker and Vault credentials, uses an EtherHiding Ethereum wallet as a durable dead-drop to fetch its rotating C2 domain, and republishes itself into other packages the victim controls. The writeup includes affected package versions, file hashes, C2 indicators, and concrete remediation guidance (pin to 0.5.143, rotate credentials, disable install scripts).

GHSA-v234-4jrq-mgg6 discloses that Claude Desktop for macOS (versions >=1.1.3918, less than 1.15962.0) omitted a macOS-executable file type from its Cowork folder block-list, letting a malicious file written into a Cowork sandbox's shared folder by a compromised or prompt-injected agent run commands on the host when opened via Claude Desktop. A separate, compounding issue is also disclosed: Cowork VM images before 1.11847.5 shipped a guest Linux kernel vulnerable to CVE-2026-43284, which combined with the block-list gap could let VM-privileged code trigger the file open without user interaction. Both issues are fixed in Claude Desktop 1.15962.0; reported internally by Anthropic and independently by Vladimir Tokarev of Cyera Research.

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.

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.
