Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The sn-releases crate, all versions, has a path traversal flaw in extract_release_archive: archive entry names are used to build output paths without checking for traversal, so a malicious release archive can write files and create directories outside the destination directory. The source gives few details on how the archive is supplied to the victim. No fix is listed, and the crate is unmaintained, so users should avoid extracting untrusted archives with it.
