CVE-2026-5479 wolfssl
In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in wolfSSLEVPCipherFinal (and related EVP cipher finalization functions) fails to verify the authentication tag before returning plaintext to the caller. When an application uses the EVP API to perform ChaCha20-Poly1305 decryption, the implementation computes or accepts the tag but does not compare it against the expected value.
