How to fix?

Upgrade libcurl to version 7.86.0 or higher.

Overview

Affected versions of this package are vulnerable to Expected Behavior Violation when doing HTTP(S) transfers, where curl might erroneously use the read callback (CURLOPT_READFUNCTION) to ask for data to send, even when the CURLOPT_POSTFIELDS option has been set if it previously used the same handle to issue a PUT request which used that callback.
