| CVE-2026-66749 | 1 Sdelements | 1 Lets-chat | 2026-07-28 | 6.5 Medium |
| Let's Chat 0.4.0 through 0.4.8 contains a null dereference vulnerability that allows authenticated attackers to crash the server by supplying a valid 24-character hex string room parameter that matches no document in the database. Attackers can send a crafted GET /messages request causing an uncaught TypeError in an asynchronous Mongoose callback that terminates the Node.js server process, with the same defect reachable through multiple code paths including the socket.io interface. | ||||
| CVE-2026-66750 | 1 Sdelements | 1 Lets-chat | 2026-07-28 | 4.3 Medium |
| Let's Chat 0.3.0 through 0.4.8 contains a broken access control vulnerability that allows authenticated attackers to download file attachments from private and password-protected rooms they are not a member of by exploiting missing room membership checks in the file retrieval route. Attackers can enumerate adjacent MongoDB ObjectIds derived from a known file ID to recover files uploaded by other users, as the GET /files/:id/:name route in app/controllers/files.js only enforces login authentication without consulting room membership or the Room.canJoin check. | ||||
| CVE-2026-66751 | 1 Sdelements | 1 Lets-chat | 2026-07-28 | 5.4 Medium |
| 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. | ||||
