NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl4-32bit package and not the libcurl4-32bit package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

An ftp:// transfer configured with CURLUSESSL_NONE can reuse a pooled FTP control connection that a previous easy handle upgraded with STARTTLS and authenticated using a client certificate. The second handle performs neither a new TLS handshake nor a new FTP login, so the server continues to authorize it under the first handle's certificate identity.
