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.","state":0,"publishedAt":"2026-10-26T16:30:30.954+00:00","modifiedAt":"2026-10-26T16:30:30.954+00:00","affected":[{"ecosystem":"Vendor product","name":"zip2","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"zip-rs\",\n                    \"product\": \"zip2\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.6.0, < 9.0.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","score":6.5,"severity":"MEDIUM"}],"references":["https://github.com/zip-rs/zip2/security/advisories/GHSA-8hxf-qr8p-62x4","https://github.com/zip-rs/zip2/commit/ec265db0b0602f8ffb9479327397bddefb7e2216","https://github.com/zip-rs/zip2/releases/tag/v9.0.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-115906","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-115906","identifiers":["CVE-2026-115906"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
