curl: TLS session cache key omits native_ca_store: a session validated with CURLSSLOPT_NATIVE_CA can be resumed by a transfer that disabled it (incomplete f

Summary CVE-2026-11564 fixed the connection pool so that a connection whose certificate was validated with the native CA store is not reused by a later transfer that switched to custom CA material. That same field, nativecastore, is compared for connection reuse but is NOT part of the TLS session...

CVE-2026-109383 undici vulnerable to TLS certificate validation bypass via dropped tls options in Agent

undici is an HTTP client library for Node.js. In versions 4.0.0 through 6.29.0, 7.0.0 through 7.30.0, and 8.0.0 through 8.12.1, its Agent dispatcher passes its constructor options through a JSON-based deep clone before forwarding them to each per-origin pool, and because JSON cannot represent...

CVE-2026-109383

The undici HTTP client library for Node.js (versions 4.0.0-6.29.0, 7.0.0-7.30.0, and 8.0.0-8.12.1) is vulnerable to Improper Certificate Validation (CWE-295).
