Missing Cryptographic Step

Overview Affected versions of this package are vulnerable to Missing Cryptographic Step in the AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 provider cipher implementations. An attacker can forge an empty message with arbitrary AAD under a key they do not know, because the expected tag is computed on...

CVE-2026-45445

Issue summary: When an application drives an AES-OCB context through the public EVPCipher one-shot interface, the application-supplied initialisation vector IV is silently discarded. Impact summary: Every message encrypted under the same key uses the same effective nonce regardless of the IV...
