Low [CVE-2026-80230] Public key pinning bypass allows unauthenticated connections
CVE-2026-80230Source published Source updated
When `CURLOPT_PINNEDPUBLICKEY` is configured alongside options that disable standard peer verification (`CURLOPT_SSL_VERIFYPEER = 0` and `CURLOPT_SSL_VERIFYHOST = 0`), libcurl fails to enforce public key pinning on connections established without a presented server certificate. Bypassing the pinning check under these disabled-verification conditions allows unauthenticated connections to succeed when they should be rejected. A flaw was found in libcurl, a client-side URL transfer library. This bypass enables unauthenticated connections that should have been rejected, potentially compromising the integrity of the connection. This Low impact flaw in curl arises when public key pinning is enabled alongside explicitly disabled SSL/TLS peer verification. In such an atypical and insecure…

- Mitigation guidance
- To mitigate this issue, ensure that SSL/TLS peer verification is enabled by setting `CURLOPT_SSL_VERIFYPEER` and `CURLOPT_SSL_VERIFYHOST` to `1` (or not explicitly disabling them). This ensures that libcurl properly enforces public key pinning and validates server certificates.
