— Security researcher Ari Marzouk disclosed 30+ vulnerabilities (24 CVEs) affecting Cursor, GitHub Copilot, Windsurf, Zed, Kiro, Roo Code, Junie, and Cline. The devastating finding: every tested AI IDE is vulnerable because none accounts for autonomous LLM agent behavior in their threat model. Universal attack chains enable RCE and data exfiltration across all tools. Separately, Zed shipped two symlink sandbox escape CVEs (CVE-2026-27967, CVE-2026-27976). Builder action: treat your IDE as an untrusted execution environment. (SC Media, GitHub Advisory)
