GHSA-rm67-g9ch-vxff: Poweradmin: Broken access control (IDOR): any zone owner can modify DNS records in zones they do not own

When you save a record edit, Poweradmin checks whether you’re allowed to touch the record by looking at a zone id you send in the POST body, but it then applies the change to a record id you also send in the POST body. Nothing checks that the record id actually belongs to that zone id. So you point the permission check at a zone you legitimately own, point the record id at somebody else’s record, and the update goes through.

A low-privilege “Editor” who only owns attacker.example was able to overwrite a record living in victim.example (owned by the admin), even though the same account gets a flat “you do not have permission to access this zone” if it tries to open that zone directly.
