CLEANSTART-2026-AU05968 PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name

Security vulnerability affects the php package. PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name...

PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN w...

CVE-2026-50166

Kuma is a modern Envoy-based service mesh that can run on every cloud across both Kubernetes and VMs. Prior to 2.7.26, 2.9.16, 2.11.14, 2.12.11, and 2.13.7, a kumactl profile manually configured for an HTTPS control plane without --ca-cert-file disables TLS peer verification and sends API tokens...

AZL-99789 CVE-2026-80230 affecting package mysql 8.0.46-1

When CURLOPTPINNEDPUBLICKEY is configured alongside options that disable standard peer verification CURLOPTSSLVERIFYPEER = 0 and CURLOPTSSLVERIFYHOST = 0, libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check und...

CVE-2026-80230 OpenSSL pinning bypass

When CURLOPTPINNEDPUBLICKEY is configured alongside options that disable standard peer verification CURLOPTSSLVERIFYPEER = 0 and CURLOPTSSLVERIFYHOST = 0, libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check und...

CVE-2026-85221 MISP CurlClient TLS Peer Verification Disabled by Default Enables Man-in-the-Middle Attacks

MISP contains an improper TLS certificate validation vulnerability in CurlClient. The CurlClient::$verifyPeer property was not explicitly initialized and therefore defaulted to null. When passed to cURL, this value effectively disabled TLS peer verification unless the calling code explicitly...

curl: curl: Public key pinning bypass allows unauthenticated connections

A flaw was found in libcurl, a client-side URL transfer library. When public key pinning is configured, but standard peer verification is explicitly disabled, libcurl incorrectly allows connections to proceed without enforcing the public key pinning. This bypass enables unauthenticated connection...

CVE-2026-18679: Improper Certificate Validation

When kuma-dp is started against an HTTPS control plane and the operator did not pass a CA certificate, the data plane connects with TLS peer verification disabled, and the dataplane authentication token is sent over that unverified connection. An on-path actor can intercept the dataplane...

curl: mbedTLS / wolfSSL / rustls backends silently skip hostname verification when CURLOPT_SSL_VERIFYPEER=0

Summary When an application sets CURLOPTSSLVERIFYPEER=0 while keeping CURLOPTSSLVERIFYHOST=2 the default, the mbedTLS, wolfSSL, and rustls TLS backends silently skip the hostname-vs-certificate check. The OpenSSL, GnuTLS, and Schannel backends correctly preserve hostname checking under the same...
