CVE-2026-82208
CVE-2026-82208 · wolfSSL CA-cache hit overrides callback
This page contains facts from public vulnerability sources. Check the original advisory before updating.
With the wolfSSL backend, when CA caching is enabled and an `CURLOPT_SSL_CTX_FUNCTION` callback replaces the trust store, libcurl can silently reinstall the cached store after the callback returns. A certificate trusted by the cached store but rejected by the callback-selected store is then incorrectly accepted.
