{"id":"RUSTSEC-2026-0297","summary":"`unzip`: archive extraction is vulnerable to path traversal (zip-slip)","details":"### Summary\n\n`Unzipper::unzip` extracts each archive entry to a path built from the entry's\n**raw, attacker-controlled name** without any traversal check. A ZIP archive whose\nentry names contain `../` components (or an absolute path) can therefore cause\nfiles to be written **outside** the destination directory chosen by the caller —\na \"zip-slip\" / directory-traversal arbitrary file write (CWE-22 / CWE-23 /\nCWE-36).\n\n### Affected versions\n\nAll published versions are affected. `unzip` has only ever released `0.1.0`\n(published 2017-12-23) and appears unmaintained, so **no fixed version is\navailable**.\n\n### Proof of concept\n\nA malicious archive with a single entry named `../ESCAPED.txt` extracted via\n`Unzipper::unzip` writes `ESCAPED.txt` one level above the destination directory.","modified":"2026-09-21T15:30:02.907499769Z","published":"2026-09-09T12:00:00Z","database_specific":{"license":"CC0-1.0"},"references":[{"type":"PACKAGE","url":"https://crates.io/crates/unzip"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2026-0297.html"},{"type":"PACKAGE","url":"https://crates.io/crates/unzip"}],"affected":[{"package":{"name":"unzip","ecosystem":"crates.io","purl":"pkg:cargo/unzip"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"}]}],"ecosystem_specific":{"affects":{"functions":["unzip::Unzipper::unzip"],"arch":[],"os":[]},"affected_functions":null},"database_specific":{"source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2026-0297.json","categories":["code-execution"],"cvss":null,"informational":null}}],"schema_version":"1.9.0"}
