Description
Astral uv before 0.11.6 contains a path traversal vulnerability that allows attackers to delete arbitrary files by supplying wheels with relative traversal paths in RECORD entries. Attackers can craft a malicious wheel whose RECORD references files outside the installation prefix, causing uv to delete those files when the user uninstalls the package.
