The link target bytes are passed directly to the platform symlink API, so a malicious archive can create an entry inside the destination that resolves to an attacker-chosen path outside it. This behavior was verified on macOS and Linux. On either platform, a subsequent application read or write through that extracted entry accesses the external target with the extracting process's permissions.\n\nFor further details see: https://github.com/zip-rs/zip2/security/advisories/GHSA-4v9h-p7m9-rh26","facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"published":"2026-10-09T12:00:00Z","modified":"2026-10-16T23:30:02Z","fixes":[{"ecosystem":"crates.io","package":"zip","fixed_in":["9.0.0"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"crates.io","package":"zip","ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"9.0.0"}]}]}],"references":[{"url":"https://crates.io/crates/zip","tags":["package"]},{"url":"https://rustsec.org/advisories/RUSTSEC-2026-0368.html","tags":["advisory"]}],"sources":{"osv":[{"id":"RUSTSEC-2026-0368","title":"zip: `ZipArchive::extract` creates symbolic links whose attacker-controlled targets are outside the destination directory","description":"In `zip` 9.0.0-pre2, `ZipArchive::extract` creates a symbolic link from an archive entry after validating only the output entry path.
