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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-1259","CWE-1270"],"references":["https://github.com/pterodactyl/panel/commit/7ffcd636310bb72b54bac3280d2a15e727feded7","https://github.com/pterodactyl/panel/pull/5636","https://github.com/pterodactyl/panel/security/advisories/GHSA-8r6w-3qq5-4p4r","https://github.com/pterodactyl/wings/commit/d0ddc80844479302abdaf9654de3bacd511c0f5c"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-54593","score":0.00681,"percentile":0.52155,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-8r6w-3qq5-4p4r","url":"https://osv.dev/vulnerability/GHSA-8r6w-3qq5-4p4r","summary":"Pterodactyl's improper JWT scoping allows subuser to upload files when not explicitly granted `file.create` permissions","modified":"2026-08-18T15:10:50.705650409Z","packages":[{"ecosystem":"Packagist","name":"pterodactyl/panel","purl":"pkg:composer/pterodactyl/panel","ranges":["<1.12.3"],"fixed":["1.12.3"]},{"ecosystem":"Go","name":"github.com/pterodactyl/wings","purl":"pkg:golang/github.com/pterodactyl/wings","ranges":["<1.12.2"],"fixed":["1.12.2"]}]},{"id":"GO-2026-6120","url":"https://osv.dev/vulnerability/GO-2026-6120","summary":"Pterodactyl's improper JWT scoping allows subuser to upload files when not explicitly granted `file.create` permissions in github.com/pterodactyl/wings","modified":"2026-08-18T15:00:21.779161573Z","packages":[{"ecosystem":"Go","name":"github.com/pterodactyl/wings","purl":"pkg:golang/github.com/pterodactyl/wings","ranges":["<1.12.2"],"fixed":["1.12.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
