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:15.4 relevant fixed versions and status.

An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set, if the same handle previously wasused to issue a PUT request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST.
