CVE-2026-26268Network attack vector

Host command execution via writable Git hooks

Published Feb 13, 2026 · Updated Feb 13, 2026

Missing authorization in Cursor before 2.5 allows remote authenticated users to escape the agent sandbox and execute host commands. The agent could write protected .git configuration, including hook definitions, and Git automatically ran the resulting commands when a later hook event occurred. Exploitation requires control of agent input, such as prompt injection, but no further user interaction; commands run outside the sandbox with the Cursor process's host privileges.
