Short explanation
Dulwich versions from 0.23.1 before 1.2.8 contain a path traversal vulnerability in CommitFilter._apply_index_filter(), allowing attackers to write files outside the working directory via symlinks persisting between commits.
Attackers can craft a repository where an ancestor commit's symlink redirects a descendant commit's file writes during filter_branch, enabling code execution by writing into .git/hooks.
What should be done?
- Follow vendor security advisories and guidance
- Update the affected dulwich package
- Audit repositories for suspicious symlinks
