CVE-2026-44465Public exploit

Code execution via unsanitized Git fsmonitor command

Published May 28, 2026 · Updated May 28, 2026

Command injection in Zed before 0.227.1 allows context-dependent attackers to execute code when a user opens a malicious repository. Zed invokes Git in the repository and permits its local .git/config core.fsmonitor value to be executed as a shell command without sanitization or restriction. Opening the folder is the required user interaction; the injected command runs with the Zed user's privileges and can read, alter, or delete accessible data.
