| Description | A flaw was found in flatpak-builder where Git hooks are not disabled when applying patch sources with use-git-am: true. An attacker who can provide a malicious source containing a Git post-applypatch hook can cause the hook to execute on the host during the build process, resulting in arbitrary code execution with the privileges of the user running flatpak-builder. | |
| Title | Flatpak-builder: host code execution via `git am` hook execution in patch source extraction (`use-git-am`) | |
