CVE-2026-16516

wolfSSH does not validate that the ECDSA curve identifier in a KEXDHREPLY host key blob matches the algorithm negotiated during key exchange. In ParseECCPubKey src/internal.c, the blob's algorithm string is used to derive the curve via NameToId/wcPrimeForId without checking against the negotiated...

CVE-2026-84897 wolfSSH server accepts server-to-client DH group exchange messages from an unauthenticated client, causing pre-authentication primality-test CPU exhaustion and key exchange role confusion

CVE-2026-84897

The wolfSSH server (through version 1.5.0 ) is vulnerable to CPU exhaustion and key exchange role confusion because it improperly admits server-to-client Diffie-Hellman group exchange messages from unauthenticated clients. Due to a missing direction check in IsMessageAllowedServer(), the server m...
