QID 982742

QID 982742: Nodejs (npm) Security Update for jose (GHSA-58f5-hfqc-jgch)

jose is an npm library providing a number of cryptographic operations.

[AES_CBC_HMAC_SHA2 Algorithm](https://tools.ietf.org/html/rfc7518#section-5.2) (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).

CVSS V3 rated as Medium - 5.9 severity.

CVSS V2 rated as Medium - 4.3 severity.

Solution

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`](https://github.com/panva/jose/releases/tag/v1.28.1), their v2.x dependency to [`^2.0.5`](https://github.com/panva/jose/releases/tag/v2.0.5), and their v3.x dependency to [`^3.11.4`](https://github.com/panva/jose/releases/tag/v3.11.4)
