{"id":"CVE-2021-29446","details":"jose-node-cjs-runtime is an npm package which provides a number of cryptographic functions. In versions prior to 3.11.4 the AES_CBC_HMAC_SHA2 Algorithm (A128CBC-HS256, A192CBC-HS384, A256CBC-HS512) decryption would always execute both HMAC tag verification and CBC decryption, if either failed `JWEDecryptionFailed` would be thrown. But a possibly observable difference in timing when padding error would occur while decrypting the ciphertext makes a padding oracle and an adversary might be able to make use of that oracle to decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). A patch was released which ensures the HMAC tag is verified before performing CBC decryption. The fixed versions are `\u003e=3.11.4`. Users should upgrade to `^3.11.4`.","aliases":["GHSA-rvcw-f68w-8h8h"],"modified":"2026-07-09T02:49:38.868204Z","published":"2021-04-16T22:15:14.140Z","references":[{"type":"ADVISORY","url":"https://github.com/panva/jose/security/advisories/GHSA-rvcw-f68w-8h8h"},{"type":"ADVISORY","url":"https://www.npmjs.com/package/jose-node-cjs-runtime"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/panva/jose","events":[{"introduced":"0"},{"fixed":"5a7078a4a2e0b0d069c48db94ccb4714033316f0"}],"database_specific":{"cpe":"cpe:2.3:a:jose-node-cjs-runtime_project:jose-node-cjs-runtime:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.11.4"}],"source":"CPE_RANGE"}}],"versions":["v1.28.0","v3.11.3","v3.11.2","v3.11.1","v3.11.0","v3.10.0","v3.9.0","v3.8.0","v3.7.1","v3.7.0","v3.6.2","v3.6.1","v3.6.0","v3.5.4","v3.5.3","v3.5.2","v3.5.1","v3.5.0","v3.4.0","v3.3.2","v3.3.1","v3.3.0","v3.2.0","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.2","v3.0.1","v3.0.0","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.27.3","v1.27.2","v1.27.1","v1.27.0","v1.26.1","v1.26.0","v1.25.2","v1.25.1","v1.25.0","v1.24.1","v1.24.0","v1.23.0","v1.22.2","v1.22.1","v1.22.0","v1.21.1","v1.21.0","v1.20.0","v1.19.0","v1.18.2","v1.18.1","v1.18.0","v1.17.2","v1.17.1","v1.17.0","v1.16.2","v1.16.1","v1.16.0","v1.15.1","v1.15.0","v1.14.0","v1.13.0","v1.12.1","v1.12.0","v1.11.0","v1.10.2","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.0","v1.7.0","v1.6.1","v1.6.0","v1.5.2","v1.5.1","v1.5.0","v1.4.1","v1.4.0","v1.3.0","v1.0.2","v1.0.1","v1.0.0","v0.12.0","v0.11.5","v0.11.4","v0.11.3","v0.11.2","v0.11.1","v0.11.0","v0.10.0","v0.9.2","v0.9.1","v0.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-29446.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
