CVE-2026-91769

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...

EUVD-2026-78773

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...

CVE-2026-50166: Improper Certificate Validation

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-2026-11751

A vulnerability has been identified in armeria-xds versions prior to 1.41.0, where xDS upstream TLS peer verification may be silently disabled, allowing man-in-the-middle attacks against xDS-managed upstream connections...

CVE-2026-11751: Undefined Security Weakness

A vulnerability has been identified in armeria-xds versions prior to 1.41.0, where xDS upstream TLS peer verification may be silently disabled, allowing man-in-the-middle attacks against xDS-managed upstream connections...

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...

CVE-2026-11310

X.509 trust-chain bypass in the OpenSSL compatibility certificate verifier wolfSSLX509verifycert. This affects only builds with --enable-opensslextra OPENSSLEXTRA and whose application validates certificates by calling X509verifycert with caller-supplied untrusted intermediate certificates; for...

curl: CVE-2026-9545: exposing HTTP/3 early data

Summary: When the ngtcp2 HTTP/3 backend reuses a TLS session that advertises early data support, cfngtcp2onsessionreuse initializes the HTTP/3 connection state and marks the connection filter as connected before the new QUIC/TLS handshake has completed. The request send path can then reach...

curl: TLS peer-verification bypass via mid-transfer ssl_config mutation

Hi all, We want to report a TLS peer-verification issue on current master. The trigger is narrow and requires a specific application usage pattern, but when it fires, a transfer that requests CURLOPTSSLVERIFYPEER=1 can reuse a TLS connection that was established with peer verification disabled...

CVE-2026-42312

pyload-ng contains a vulnerability (CVE-2026-42312) where a non-admin user with SETTINGS permission can disable TLS peer/hostname verification by setting general.ssl_verify off. The root cause is that the option is not in the ADMIN_ONLY_CORE_OPTIONS allowlist, so set_config_value() writes are all...

SUSE CVE-2026-43052

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: check tdls flag in ieee80211tdlsoper When NL80211TDLSENABLELINK is called, the code only checks if the station exists but not whether it is actually a TDLS station. This allows the operation to proceed for non-TDL...
