CVE-2021-29446

jose-node-cjs-runtime is an npm package which provides a number of cryptographic functions. In versions prior to 3.11.4 the AESCBCHMACSHA2 Algorithm A128CBC-HS256, A192CBC-HS384, A256CBC-HS512 decryption would always execute both HMAC tag verification and CBC decryption, if either failed...

Padding Oracle Attack

jose-node-cjs-runtime is vulnerable to padding oracle attack. The vulnerability exists as decryption did not fail as soon as hmac verification fails, allowing timing information to be measured by running the CBC decryption with various padding length...
