CVE-2026-62415Network attack vector

Unauthenticated file storage via enabled upload endpoint

Published Jul 21, 2026 · Updated Jul 21, 2026

Insecure defaults in JoomDonation Membership Pro before 4.6.2 allow remote attackers to upload files without authentication. The subscription file-upload endpoint remains enabled even when no File custom field exists and accepts requests from anonymous visitors. Any network-reachable Joomla site with the extension installed is exposed; default file-type limits prevent code execution but permit unauthorized storage.
