CVE-2025-64767

hpke-js is a Hybrid Public Key Encryption (HPKE) module built on top of Web Cryptography API. Prior to version 1.7.5, 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. This issue has been patched in version 1.7.5.

Weakness

Nonces should be used for the present occasion and only once.
