High · 8.1 Public exploit CVE-2026-26268 EUVD-2026-7368

Cursor sandbox escape via Git hooks

Published Feb 13, 2026 · Updated Feb 13, 2026 · Assigned by GitHub_M

Vendor: cursor Product: cursor

Description

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.
