CVE-2026-45446

Issue summary: The implementations of AES-SIV RFC 5297 and AES-GCM-SIV RFC 8452 mishandle the authentication of AAD Additional Authenticated Data with an empty ciphertext allowing a forgery of such messages. Impact summary: An attacker can forge empty messages with arbitrary AAD to the victim's...

@hpke/core reuses AEAD nonces

Summary The public SenderContext Seal API has a race condition which allows for the same AEAD nonce to be re-used for multiple Seal calls. This can lead to complete loss of Confidentiality and Integrity of the produced messages. Details The SenderContext Seal implementation allows for concurrent...
