The Ubuntu security team deemed this advisory irrelevant for Ubuntu:25.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Ubuntu.
URLs containing percent-encoded slashes (/ or \) can trick wcurl into
saving the output file outside of the current directory without the user
explicitly asking for it.
This flaw only affects the wcurl command line tool.
