{"id":"CVE-2026-115907","published":"2026-10-26T17:17:18.147","lastModified":"2026-10-26T18:34:17.050","description":"zip is a zip library for Rust that supports reading and writing simple ZIP files. From 5.1.0 until 9.0.0, applications built with the legacy-zip feature can reserve output capacity from an attacker-controlled ZIP64 uncompressed size before validating the compressed stream. The ShrinkDecoder path in src/legacy/shrink.rs can panic with a capacity overflow during ZipArchive::extract, and the Reduce and Implode decoders contain the same unbounded preallocation pattern. An unhandled panic can terminate an archive-processing service. This issue is fixed in version 9.0.0.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-400","CWE-789"],"vendors":[],"products":[],"references":[{"url":"https://github.com/zip-rs/zip2/commit/8b4991288b79ad11cce201c2d785d5baa795bd3e","tags":[]},{"url":"https://github.com/zip-rs/zip2/pull/991","tags":[]},{"url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0","tags":[]},{"url":"https://github.com/zip-rs/zip2/security/advisories/GHSA-9hj8-73fh-9963","tags":[]}],"exploitRefs":[{"url":"https://github.com/zip-rs/zip2/commit/8b4991288b79ad11cce201c2d785d5baa795bd3e","tags":[]},{"url":"https://github.com/zip-rs/zip2/pull/991","tags":[]},{"url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0","tags":[]},{"url":"https://github.com/zip-rs/zip2/security/advisories/GHSA-9hj8-73fh-9963","tags":[]}],"hasPoc":true,"ai":null}
