CVE-2026-27113

User-assisted code execution via unescaped Git branch names

Published Feb 20, 2026 · Updated Feb 20, 2026

Command injection in Liquid Prompt's affected master branch allows attackers to execute shell commands via crafted Git branch names. The gitstatusd paths in _lp_git_branch and _lp_git_tag copied branch and tag data into prompt variables without escaping shell syntax before rendering. Exploitation requires an affected commit, an initialized gitstatusd backend, active prompt substitution, and a user entering the compromised repository; commands run with that shell user's privileges.
