CVE-2026-42012
CVE-2026-42012 affects the GnuTLS library. A remote attacker can craft a certificate with URI or SRV SANs that causes the validator to fall back to CN checks, bypassing proper SAN validation and enabling potential impersonation/MITM. Documented in multiple advisories and patches across distros: o...
CVE-2026-42012
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier URI or Service SRV Subject Alternative Names SANs. This could cause the certificate validation process to incorrectly fall back to...
CVE-2026-42013
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...

CVE-2026-45574 epa4all-client: TLS Certificate Validation Disabled in Production
epa4all-client is the Java Client for epa4all / ePA 3.0 in the Telematik Infrastruktur. Prior to 1.2.2, an attacker on the network path between the ePA service and the Konnektor can present any TLS certificate self-signed, expired, wrong CN and intercept all SOAP traffic. This includes patient...
CVE-2026-45574
The CVE affects the epa4all-client Java library (for epa4all / ePA 3.0). Before version 1.2.2, a network-path attacker could present any TLS certificate (self-signed/expired/wrong CN) and intercept SOAP traffic, exposing KVNRs, SMC-B authentication/signing, document content, and credential exchan...

JLSEC-2026-526
A vulnerability was found in GnuTLS, where a cockpit which uses gnuTLS rejects a certificate chain with distributed trust. This issue occurs when validating a certificate chain with cockpit-certificate-ensure. This flaw allows an unauthenticated, remote client or attacker to initiate a denial of...
Apache Tomcat: Apache Tomcat: Authentication bypass via client certificate misconfiguration
A flaw was found in Apache Tomcat where OCSP-based certificate validation may incorrectly soft-fail during CLIENTCERT authentication, even when soft-fail is disabled, under certain FFM-related execution paths. This can result in client certificates being accepted despite failed or unverifiable...
gnutls: gnutls: Certificate validation bypass due to improper handling of URI and SRV SANs
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier URI or Service SRV Subject Alternative Names SANs. This could cause the certificate validation process to incorrectly fall back to...

gnutls: gnutls: Security bypass due to incorrect name constraint handling
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...
