Description
W (vincent-peugnet/wcms) through 3.18.0 contains a remote code execution vulnerability that allows authenticated editors to write arbitrary files by abusing the unvalidated path in POST /api/v0/media/upload/[*:path]. Attackers can upload .php files executed by the web server, use encoded ../ sequences to write outside the media directory, and delete arbitrary files via DELETE /api/v0/media/[*:path].
