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.
Weakness
The product does not validate, or incorrectly validates, a certificate.
