CVE-2026-53939

A flaw was found in cjose. When encrypting a JSON Web Encryption JWE object using AES-CBC-HMAC algorithms, the library initializes the encryption key with all-zero bytes instead of generating a secure random key. As a result, an attacker who intercepts the encrypted message can decrypt sensitive...

RUSTSEC-2017-0001 scalarmult() vulnerable to degenerate public keys

The scalarmult function included in previous versions of this crate accepted all-zero public keys, for which the resulting Diffie-Hellman shared secret will always be zero regardless of the private key used. This issue was fixed by checking for this class of keys and rejecting them if they are us...
