Prior to 1.35.11, 1.36.7, 1.37.3, and 1.38.1, the OAuth2 HTTP filter&#39;s encrypt()/decrypt() functions use AES-256-CBC without an authentication tag (no HMAC, no AEAD). The /callback endpoint returns HTTP 302 on successful decryption and HTTP 401 on padding failure, creating a padding oracle. An attacker who obtains the encrypted CodeVerifier cookie can recover the plaintext PKCE code_verifier in ~6,200 requests (~100 seconds), then exchange it with a stolen authorization code to obtain the victim&#39;s access token. This vulnerability is fixed in 1.35.11, 1.36.7, 1.37.3, and 1.38.1.</p> <p><strong>Affected:</strong> envoyproxy envoy</p> <p>Envoy is an open source edge and service proxy designed for cloud-native applications.
