Doc Text:
A flaw was found in wcurl. This vulnerability allows a remote attacker to manipulate the location where output files are saved. By crafting a malicious URL with percent-encoded slashes, the attacker can trick the wcurl command-line tool into writing files outside of the intended directory. This could lead to unauthorized file placement on the system.

Description OSIDB Bzimport 2026-02-25 08:01:27 UTC 
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.
