CVE-2026-5479
wolfSSL EVP ChaCha20-Poly1305 AEAD authentication tag
Summary
wolfSSL EVP ChaCha20-Poly1305 AEAD authentication tag
Original description
The description as published by the source.
In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in wolfSSL_EVP_CipherFinal (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.
