CVE-2026-26268

9.9 criticalEPSS 0.7%

Critical (9.9) in anysphere cursor. EPSS 0.7% chance of exploitation in the next 30 days.

Cursor is a code editor built for programming with AI. Sandbox escape via writing .git configuration was possible in versions prior to 2.5. A malicious agent (ie prompt injection) could write to improperly protected .git settings, including git hooks, which may cause out-of-sandbox RCE next time they are triggered. No user interaction was required as Git executes these commands automatically. Fixed in version 2.5.
