## Summary

All-in-One Video Gallery, a WordPress plugin, lets unauthenticated visitors obtain the media source of videos that are supposed to be password-protected, such as unlisted YouTube or Vimeo links and external file URLs, through its standalone player page and download link. The plugin skips the password check on those two paths, so the flaw can be reached without logging in.
