CVE-2026-84964

A double free in the OpenSSL-based TLS certificate revocation checking path of the MongoDB C Driver can be reached by a TLS endpoint that the client already trusts. During the handshake, specially formed certificate data can cause the same heap object to be released twice. An unauthenticated part...

curl: Apple SecTrust fallback ignores CURLOPT_CRLFILE, letting a revoked cert pass

When libcurl is built with USEAPPLESECTRUST and the native Apple trust store is in use, a certificate that OpenSSL/GnuTLS rejects because it is on the operator's CURLOPTCRLFILE list is re-checked by Apple's SecTrust API instead, and SecTrust is never told about that CRL file at all. The bug...

CVE-2026-85221

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...
