CWE-22  (opens in a new tab)

How to fix?

NVD Description

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

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.
