CVE-2026-54622: django CMS: Clipboard copy IDOR discloses unauthorized plugin content
The clipboard copy paths of the copy_plugins admin endpoint validate only the target (the user’s own clipboard) and skip source-side authorization. A staff user can copy plugins out of a placeholder they have no permission on into their clipboard, then read the (secret) content.
