CVE-2026-26268

Cursor sandbox escape via Git hooks

State: Published
Severity: 8.1 High
Published: Feb 13, 2026
Updated: Feb 13, 2026
Reserved: Feb 12, 2026

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.
