Warp branch selector command injection via Git branch names

Warp is an agentic development environment. From 0.2025.08.06.08.12.stable_00 until 0.2026.05.06.15.42.stable_01, Warp contains a command injection in the prompt branch selector. A user who can publish a branch to a Git repository opened in Warp can cause a crafted branch name to be interpreted by the victim's shell if the victim selects that branch from the UI. This vulnerability is fixed in 0.2026.05.06.15.42.stable_01.
