{"schema":"threatline.record/2","record":{"id":"CVE-2026-115906","aliases":["GHSA-8hxf-qr8p-62x4"],"summary":"zip: AES Entry HMAC Authentication Bypass on Premature EOF","details":"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.","categories":["Unclassified"],"product":"zip2","vendor":"zip-rs","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-115906","source_modified_at":"2026-10-26T16:30:30.954Z","fetched_at":"2026-10-26T19:10:57.178988Z","product":"zip2","vendor":"zip-rs","versions":[{"version":">= 0.6.0, < 9.0.0","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":6.5,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-26T16:30:30.954Z","modified_at":"2026-10-26T16:30:30.954Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-115906","fetched_at":"2026-10-26T19:10:57.178988Z","source_modified_at":"2026-10-26T16:30:30.954Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/zip-rs/zip2/security/advisories/GHSA-8hxf-qr8p-62x4","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/zip-rs/zip2/commit/ec265db0b0602f8ffb9479327397bddefb7e2216","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/zip-rs/zip2/releases/tag/v9.0.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-26T16:30:30.954Z","content_hash":"33e38a7a22da81f41d0daa83f745df4f57f2f72f2d197b9d62f17871f470affe"}}
