NVD Description

Note: Versions mentioned in the description apply only to the upstream libcurl4 package and not the libcurl4 package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A vulnerability exists where a connection requiring TLS incorrectly reuses an existing unencrypted connection from the same connection pool. If an initial transfer is made in clear-text (via IMAP, SMTP, or POP3), a subsequent request to that same host bypasses the TLS requirement and instead transmit data unencrypted.
