CVE-2021-29443

jose is an npm library providing a number of cryptographic operations. In vulnerable versions AESCBCHMACSHA2 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.

CVE-2021-29443

CVE-2021-29443 affects the jose npm library. Vulnerable versions of the library perform HMAC tag verification after attempting CBC decryption, creating a possible padding oracle through observable timing differences during decryption of AES_CBC_HMAC_SHA2 (A128CBC-HS256, A192CBC-HS384, A256CBC-HS5...
