GHSA-FQFH-778M-2V32

Vulnerability from github – Published: 2022-02-11 23:41 – Updated: 2021-05-21 22:06
VLAI
Summary
GitHub CLI can execute a git binary from the current directory
Details

Impact

GitHub CLI depends on a git.exe executable being found in system %PATH% on Windows. However, if a malicious .\git.exe or .\git.bat is found in the current working directory at the time of running gh, the malicious command will be invoked instead of the system one.

Windows users who run gh inside untrusted directories are affected.

Patches

Users should upgrade to GitHub CLI v1.2.1.

Workarounds

Other than avoiding untrusted repositories, there is no workaround.
