Prior to Panel version 1.12.3 and Wings version 1.12.2, the Wings /upload/file endpoint accepted any valid panel-signed JWT that contained server_uuid, user_uuid, and unique_id claims without checking the token's intended purpose; because the Panel issues JWTs carrying those same claims for lower-privilege operations such as WebSocket authentication and file-download links, an authenticated subuser could reuse one of those tokens (for example a WebSocket token obtained with only the websocket.connect permission) by replaying it against /upload/file to write arbitrary files to the same server, despite never being granted the file.create permission. This issue is fixed in Panel version 1.12.3 and Wings version 1.12.2.","state":0,"publishedAt":"2026-07-28T15:42:56.971+00:00","modifiedAt":"2026-07-28T16:39:43.359+00:00","affected":[{"ecosystem":"Vendor product","name":"panel","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"pterodactyl\",\n                    \"product\": \"panel\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 1.12.3\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H","score":8.1,"severity":"HIGH"}],"references":["https://github.com/pterodactyl/panel/security/advisories/GHSA-8r6w-3qq5-4p4r","https://github.com/pterodactyl/panel/pull/5636","https://github.com/pterodactyl/panel/commit/7ffcd636310bb72b54bac3280d2a15e727feded7","https://github.com/pterodactyl/wings/commit/d0ddc80844479302abdaf9654de3bacd511c0f5c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54593","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54593","identifiers":["CVE-2026-54593"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
