Attackers can mint near-permanent administrator tokens that survive password changes, retaining full control of the dashboard since tokens are verified only against a static JWT secret that is never rotated.","published":"2026-09-25T22:17:11.000Z","lastModified":"2026-09-30T16:39:30.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":5.9,"severity":"MEDIUM","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-613"],"affected":[],"epss":{"score":0.00364,"percentile":0.30038,"date":"2026-10-27","history":[{"date":"2026-09-26","score":0.00289,"percentile":0.19286}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.36%).
