When a user opens the malicious repository and sends any message, the agent triggers a git status index refresh which executes the injected command in the user's process context, exposing the full environment including configured provider API keys.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":61,"depthScoreParts":{"impact":48.4,"likelihood":0.2,"exploitation":12,"ransomware":0},"changes":[{"seq":211917,"id":"CVE-2026-71963","ts":1790601614272,"field":"exploit_available","old":"false","new":"true"}]}
