YesWiki before 4.6.7 contains an unrestricted file upload vulnerability that allows authenticated admins to write remote files into the web-accessible files/ directory via Bazar CSV import preview. Attackers can import a CSV whose file or image field references a remote .php URL, which is saved without extension checks and executed as server-side code.
