Description
Let's Chat 0.3.0 through 0.4.8 contains an improper authorization vulnerability that allows any authenticated user to archive any room on the server by sending a DELETE request to the rooms handler without ownership verification. Attackers can enumerate room IDs via the rooms listing endpoint and permanently archive private or password-protected rooms they cannot access, with no application-level recovery path requiring direct database intervention to restore.
