How to fix?

Upgrade SLES:15.7 wcurl to version 8.22.0-150700.7.33.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream wcurl package and not the wcurl package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

Enabling CURLOPT_CRLF causes curl to advertise the raw input byte count in the IMAP APPEND {N} literal while transmitting line-ending expanded data. The server reads only $N$ bytes for the payload, causing the remaining overflow bytes to be interpreted and executed as pipelined IMAP commands within the authenticated session.
