How to fix?

There is no fixed version for Debian:13 curl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Debian. See How to fix? for Debian:13 relevant fixed versions and status.

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.
