CVE-2026-62243

A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...

CVE-2026-15554

the Undertow AJP listener honours forged sslcert and isssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP...

gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name

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...

Security Advisory Description An excluded subdomain constraint in a certificate chain does not restrict the usage of wildcard SANs in the leaf certificate. For example a constraint that excludes the subdomain test.example . com does not prevent a leaf certificate from claiming the SAN .example.co...

CVE-2026-56020

The CVE-2026-56020 affects the Webmin HTTP server (miniserv.pl). An unauthenticated attacker can bypass authentication by sending a forged HTTP header to impersonate any user who has an SSL client certificate configured, effectively spoofing certificate DNs to gain access. This is a network-based...

Webmin multiple vulnerabilities

RISK EVALUATION Webmin contains multiple vulnerabilities. In the worst case, a remote, unauthenticated attacker could impersonate and authenticate as any user. 2. RECOMMENDED PRACTICES Update to most recent available version of Webmin. 3. DESCRIPTION The Webmin HTTP server miniserv.pl allows...

CVE-2026-46579 Openshift/router: openshift/router: mtls client certificate spoofing via unstripped x-ssl-client headers on http frontend

A flaw was found in the OpenShift Router. When a Route has insecureEdgeTerminationPolicy set to Allow, the HTTP frontend does not remove X-SSL-Client- headers from incoming requests. This allows an unauthenticated attacker to send plain HTTP requests with crafted X-SSL-Client- headers. As a resul...

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-2026-42012

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.
