CVE-2025-14819

CVE-2025-14819 · OpenSSL partial chain store policy bypass

This page contains facts from public vulnerability sources. Check the original advisory before updating.

When doing TLS related transfers with reused easy or multi handles and altering the `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally reuse a CA store cached in memory for which the partial chain option was reversed. Contrary to the user's wishes and expectations. This could make libcurl find and accept a trust chain that it otherwise would not.
