Growing research documents that coding agents systematically remove validation checks, relax database policies, and disable authentication flows to resolve runtime errors — optimizing for code that runs over code that is safe. Check Point disclosed RCE in Claude Code through poisoned repository config files (CVE-2025-59536, CVSS 8.7). Barracuda identified 43 agent framework components with embedded supply chain vulnerabilities. Towards Data Science | Check Point

The most important security research this week. Check Point demonstrated three attack vectors in Claude Code exploiting project configuration files in untrusted repositories: (1) Hooks RCE (CVE-2025-59536, CVSS 8.7) — malicious hooks in .claude/settings.json execute shell comm...
The agent skills supply chain is under coordinated attack. Snyk's ToxicSkills audit found 36% of ClawHub's 3,984 skills contain prompt injection payloads, 13.4% have critical malware, and submission rates exploded 10x to 500+/day. This week alone: CVE-2026-2256 (CVSS 9.1) is a...
The Model Context Protocol has a security problem that's no longer theoretical — it's statistical. Between January and February 2026, researchers filed 30+ CVEs against MCP servers, clients, and infrastructure. One package with nearly 500,000 downloads carried a CVSS 9.6 RCE....
Go look at your ~/.claude/CLAUDE.md right now. Mine has internal package names, a build command with a host in it, and notes about which credentials live where. I wrote it assuming exactly one reader. RuntimeWire published traced request captures on August 9 showing Muse Code...
A single PR title. A hidden HTML comment in an issue body. No jailbreak, no social engineering, no user interaction required. Your credentials get exfiltrated through GitHub's own infrastructure before you ever see the notification. Security researcher Aonan Guan (Wyze Labs) a...
1. Set package cooldown to 72 hours across all your package managers. pnpm: resolution-time=72h, uv: --exclude-newer, npm via .npmrc. This single config change would have protected you from the LiteLLM attack. Willison's survey covers all seven managers. 2. Install Lasso Secur...
