Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.35.11, 1.36.7, 1.37.3, and 1.38.1, the OAuth2 HTTP filter's encrypt/decrypt functions use AES-256-CBC without an authentication tag no HMAC, no AEAD. The /callback endpoint returns HTTP 302 on...

EUVD-2026-39571

PKCS12 MAC verification uses an attacker-controlled comparison length, weakening the integrity check on the MAC and allowing a mismatched MAC to be accepted. The PKCS12 verify path compared the locally computed HMAC against the MAC parsed from the PKCS12 structure using a length taken directly fr...

CVE-2026-6331

HMAC zero-length tag forgery in EVPDigestVerifyFinal, where a zero-length tag could be accepted as valid during HMAC verification. In the OpenSSL-compatibility HMAC verify path the supplied signature length was only checked as not exceeding the MAC length, so a zero-length or otherwise truncated...
