GHSA-58f5-hfqc-jgch Padding Oracle Attack due to Observable Timing Discrepancy in jose

• npm jose: >= 1.0.0, < 1.28.1 → fixed in 1.28.1 • npm jose: >= 2.0.0, < 2.0.5 → fixed in 2.0.5 • npm jose: >= 3.0.0, < 3.11.4 → fixed in 3.11.4

jose is an npm library providing a number of cryptographic operations. Impact 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). Patches All major release versions have had a patch released which ensures the HMAC tag is verified before performing CBC decryption. The fixed versions are `^1.28.1 || ^2.0.5 || >=3.11.4`. Users should upgrade their v1.x dependency to `^1.28.1`, their v2.x dependency to `^2.0.5`, and their v3.x dependency to `^3.11.4` Credits Thanks to Morgan Brown of Microsoft for bringing this up and Eva Sarafianou (@esarafianou) for helping to score this advisory.
