CVE-2026-89134 Subject CN name-constraint check bypassed when non-DNS SAN present

A certificate with no dNSName SAN but another SAN type present e.g. registeredID or iPAddress bypassed the Subject CN dNSName name-constraint check. The CN-as-DNS fallback was gated on cert-subjectCN != NULL && cert-altNames == NULL && !cert-isCA instead of "no dNSName SAN", so an out-of-scope CN...

CVE-2026-89134

The wolfSSL library (version 5.9.2 ) is vulnerable to a bypass of the Subject CN dNSName name-constraint check . This issue arises because the CN-as-DNS fallback was incorrectly gated on the absence of all alternative names (cert->altNames == NULL) rather than specifically checking for the abs...

CVE-2026-94418

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-2026-89135 Failed X509_verify_cert leaves unverified CA in shared CertManager

A failed X509verifycert call permanently plants an unverified attacker CA in the shared CertManager, bypassing certificate validation in every type-blind sibling consumer native TLS, OCSP, CRL, direct CM verify. This affects version 5.8.4 through 5.9.2 of wolfSSL with the macros OPENSSLEXTRA &&...

CVE-2026-89135

The wolfSSL library, versions 5.8.4 through 5.9.2 , is vulnerable to a flaw where a failed X509_verify_cert call permanently installs an unverified attacker Certificate Authority (CA) into the shared CertManager . This allows an attacker to bypass certificate validation across various consumers, ...

EUVD-2026-87908

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-2026-100665

A flaw was found in Netty. During certificate validation for Quick UDP Internet Connections QUIC, standard trust managers fail to perform endpoint identification to confirm the server's identity. A remote attacker positioned on the network path can exploit this flaw by presenting a valid...

CVE-2026-93302: Improper Certificate Validation

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-2026-100835: Improper Certificate Validation

Contrast before 1.16.0 is susceptible to remote attestation relay attacks. Contrast accepted any TEE attestation report that verified correctly and contained the expected firmware patch levels and software measurements, regardless of which machine produced it, so attestation was not bound to...

CVE-2026-89133: Improper Certificate Validation

wolfSSL versions 5.9.2 and earlier contain a flaw in the X.509 certificate validation logic where it fails to properly enforce NameConstraints extensions when there is an unconstrained CA tier between a name-constrained intermediate CA and the leaf certificate. wolfSSL incorrectly accepted...
