{"id":"CVE-2026-115906","published":"2026-10-26T17:17:17.993","lastModified":"2026-10-26T18:39:42.503","description":"zip is a zip library for Rust that supports reading and writing simple ZIP files. From 0.6.0 until 9.0.0, the AES entry reader in src/aes.rs verifies its HMAC only when the attacker-controlled data counter reaches zero. If the underlying bounded reader reaches the real end of the archive while data_remaining is still positive, or if an encrypted entry has no payload, the reader can return a clean end of stream without reading and comparing the authentication tag. Applications using by_index_decrypt, by_name_decrypt, by_path_decrypt, or password-enabled by_index_with_options can therefore accept modified plaintext without an authentication error. This issue is fixed in version 9.0.0.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","cwes":["CWE-354","CWE-1284"],"vendors":[],"products":[],"references":[{"url":"https://github.com/zip-rs/zip2/commit/ec265db0b0602f8ffb9479327397bddefb7e2216","tags":[]},{"url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0","tags":[]},{"url":"https://github.com/zip-rs/zip2/security/advisories/GHSA-8hxf-qr8p-62x4","tags":[]}],"exploitRefs":[{"url":"https://github.com/zip-rs/zip2/commit/ec265db0b0602f8ffb9479327397bddefb7e2216","tags":[]},{"url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0","tags":[]},{"url":"https://github.com/zip-rs/zip2/security/advisories/GHSA-8hxf-qr8p-62x4","tags":[]}],"hasPoc":true,"ai":null}
