CVE-2026-93302

MatchTrustedPeer ignores the public key used, leading to forged CA clones passing verification. Affected builds are any that enable the macro WOLFSSLTRUSTPEERCERT and load CA certificates with wolfSSLCTXtrustpeercert or wolfSSLtrustpeercert. The peer must know the certificates being loaded to...

CVE-2026-93302

The wolfSSL library contains a vulnerability where the MatchTrustedPeer function ignores the public key during verification, allowing forged CA clones to pass. This affects builds enabling the WOLFSSL_TRUST_PEER_CERT macro and loading certificates via wolfSSL_CTX_trust_peer_cert() or wolfSSL_trus...

CVE-2026-93304 (D)TLS 1.2 client accepts early ChangeCipherSpec before ClientKeyExchange

A DTLS 1.2 client can accept a ChangeCipherSpec message before it has sent its ClientKeyExchange. No master secret has been derived at that point, so the client installs read keys derived from a known deterministic key and checks the server's Finished against that same key. An out-of-order...

CVE-2026-93304

A (D)TLS 1.2 client is vulnerable to an out-of-order ChangeCipherSpec message being accepted before the ClientKeyExchange is sent. Because the master secret is not yet derived, the client installs read keys from a known deterministic key, allowing a man-in-the-middle attacker to complete the hand...

CVE-2026-94417 CRL check skipped when OCSP enabled and certificate has no OCSP URL

When an application enables both OCSP and CRL revocation checking on one WOLFSSLCTX or certificate manager, wolfSSL skips the CRL check for any peer certificate that carries no Authority Information Access OCSP URL, and accepts a certificate the loaded CRL lists as revoked. The soft-fail policy f...

CVE-2026-94417

The wolfSSL library (all versions from 5.9.2 and earlier ) is vulnerable to a certificate revocation bypass when both OCSP and CRL checking are enabled. The flaw exists in ProcessPeerCerts() , where a soft-fail policy for missing OCSP responders causes the system to skip CRL checks for peer certi...

CVE-2026-94418 Signature failure masked by date error under WOLFSSL_SMALL_CERT_VERIFY

Under WOLFSSLSMALLCERTVERIFY, ProcessPeerCertParse runs the certificate signature check separately from the parse to keep peak memory down, then merges the two results, but it merged the signature result back only when the parse returned 0, so any parse error hid it. ParseCertRelative reaches its...
