CVE-2026-94417

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...

CVE-2026-94418

WolfSSL is vulnerable to a cryptographic signature verification bypass when the WOLFSSL_SMALL_CERT_VERIFY option is enabled. The ProcessPeerCertParse() function separates signature checks from parsing to save memory but fails to merge the signature result if a parse error occurs, effectively hidi...

CVE-2026-94419

The wolfSSL library (releases v5.3.0 through v5.9.2 ) is vulnerable to client session cache reference poisoning. Due to missing checks on the process-global SessionCache , an attacker can overwrite a client-side entry by providing a matching TLS 1.2 session ID sent in clear. This allows an attack...
