These names are stored in the consent\nstatistics and rendered without output encoding in the administration\nbackend. An unauthenticated remote attacker can thereby inject script code that\nis executed in the browser session of an administrator viewing the consent\nstatistics page, allowing actions to be performed with the administrator's\nprivileges.","published":"2026-10-14T11:16:59.000Z","lastModified":"2026-10-16T20:04:30.000Z","status":"Deferred","sourceIdentifier":"a6d3dc9e-0591-4a13-bce7-0f5b31ff6158","cvss":{"version":"4.0","score":8.6,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:N/SC:L/SI:L/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-79"],"affected":[],"epss":{"score":0.00404,"percentile":0.34452,"date":"2026-10-27","history":[{"date":"2026-10-15","score":0.00404,"percentile":0.33014}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.40%).
