CVE-2026-42790
Improper Certificate Validation vulnerability in Erlang OTP publickey pubkeycert and publickey modules allows a DNS nameConstraints bypass via subject CommonName fallback in TLS hostname verification. Two flaws combine to allow a subordinate CA whose DNS nameConstraints are restricted e.g...
CVE-2026-40944
Oxia is a metadata store and coordination system. Prior to 0.16.2, the trustedCertPool function in the TLS configuration only parses the first PEM block from CA certificate files. When a CA bundle contains multiple certificates e.g., intermediate + root CA, only the first certificate is loaded...
Linux Distros Unpatched Vulnerability : CVE-2026-35563
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - It was identified that the LDAP client implementation in version 2.1.7 does not verify if the server certificate matches the intended LDAP hostname. While the...
CVE-2026-35563
It was identified that the LDAP client implementation in version 2.1.7 does not verify if the server certificate matches the intended LDAP hostname. While the underlying code validates the certificate chain against a trusted authority, the absence of endpoint identification allows a valid...

CVE-2026-35563 Apache Directory LDAP API: LDAP client implementation does not verify if the server certificate matches the intended LDAP hostname
It was identified that the LDAP client implementation in version 2.1.7 does not verify if the server certificate matches the intended LDAP hostname. While the underlying code validates the certificate chain against a trusted authority, the absence of endpoint identification allows a valid...
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...
GHSA-PGH9-MPWC-8JJF Harvester's SUSE Virtualization Registration Client Vulnerable to MITM and DOS
Impact A vulnerability has been identified in the SUSE Virtualization Harvester Rancher integration mechanism where by default the registration client uses an insecure TLS option that fails to verify the remote server’s certificate. This security gap could allow the execution of a man-in-the-midd...
Improper Certificate Validation
Caddy is vulnerable to Improper Certificate Validation. The vulnerability is due to swallowed errors in ClientAuthentication.provision, where failures loading trustedcacertfile or trustedcacertspemfiles are ignored, causing mTLS authentication to fail open and accept any client certificate signed...

GHSA-7JRQ-Q4PQ-RHM6 Oxia's TLS CA certificate chain validation fails with multi-certificate PEM bundles
Summary The trustedCertPool function in the TLS configuration only parses the first PEM block from CA certificate files. When a CA bundle contains multiple certificates e.g., intermediate + root CA, only the first certificate is loaded. This silently breaks certificate chain validation for mTLS...
CVE-2026-34477 Apache Log4j Core: verifyHostName attribute silently ignored in TLS configuration, allowing hostname verification bypass
The fix for CVE-2025-68161 https://logging.apache.org/security.htmlCVE-2025-68161 was incomplete: it addressed hostname verification only when enabled via the log4j2.sslVerifyHostName https://logging.apache.org/log4j/2.x/manual/systemproperties.htmllog4j2.sslVerifyHostName system property, but no...
SUSE CVE-2026-33810
When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

Allocation of Resources Without Limits or Throttling
Overview std/crypto/x509 is a Go standard library package std/crypto/x509 Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling. Go Vulnerability Report: Validating certificate chains which use policies is unexpectedly inefficient when certificat...
CVE-2026-33248
A flaw was found in NATS-Server, a high-performance messaging system. When configured to use mutual Transport Layer Security mTLS for client identity, and specifically the verifyandmap feature, certain patterns within a client certificate's Subject Distinguished Name DN were not correctly enforce...
CVE-2026-33248 NATS has mTLS verify_and_map authentication bypass via incorrect Subject DN matching
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, when using mTLS for client identity, with verifyandmap to derive a NATS identity from the client certificate's Subject DN, certain patterns of RDN would not be...
