YesWiki before 4.6.7 contains a missing authorization flaw in the pointimage action (tools/attach/actions/pointimage.php), which saves content to an attacker-chosen page with write ACL checks bypassed. Unauthenticated attackers can POST pagetag, title, and description fields to any page rendering {{pointimage}} to append raw HTML or JavaScript to any wiki page, including pages whose write ACL restricts editing, causing stored cross-site scripting in viewers' and administrators' browsers.
