CVE-2026-47778
A flaw was found in Envoy, an open-source edge and service proxy. A remote attacker could exploit a structural flaw in the DefaultCertValidator::verifySubjectAltName function by presenting a specially crafted certificate. This certificate would contain a NUL byte within its DNS Subject Alternativ...
crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application
A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...
crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation
A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...
CVE-2026-12374
CVE-2026-12374 affects the macOS PrivilegedHelperTool in Cato Client prior to v5.13.1. The issue combines improper XPC caller certificate validation with a TOCTOU race, allowing a local authenticated attacker to escalate to root by using a self-signed certificate that bypasses XPC caller verifica...
EUVD-2026-41001
Improper certificate validation and a time-of-check time-of-use TOCTOU race condition in the PrivilegedHelperTool XPC service in Cato Client before v.5.13.1 on macOS allows a local authenticated attacker to escalate privileges to root via a self-signed certificate that bypasses the XPC caller...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption
A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...

Linux Distros Unpatched Vulnerability : CVE-2026-55960
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Un-negotiated Raw Public Key RFC 7250 accepted in place of an X.509 certificate, bypassing chain validation. A raw public key has no chain, so ParseCertRelative...
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...
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...
