{"id":"CVE-2025-4123","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-4123","generatedAt":"2026-11-03T20:38:24.908Z","title":"A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect.","description":"A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF.\n\nThe default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive.","published":"2025-05-22T08:15:53.000Z","lastModified":"2026-06-17T09:32:33.000Z","status":"Modified","sourceIdentifier":"security@grafana.com","cvss":{"version":"3.1","score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-79","CWE-601"],"affected":["grafana/grafana"],"epss":{"score":0.97083,"percentile":0.99892,"date":"2026-11-02","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":false,"firstPublished":"2026-04-06","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":52491,"kind":"exploit","title":"Grafana 11.6.0 - SSRF","url":"https://www.exploit-db.com/exploits/52491","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/multiple/webapps/52491.txt","file":"exploits/multiple/webapps/52491.txt","published":"2026-04-06","added":"2026-04-06","updated":"2026-04-06","author":"Beatriz Fresno Naumova","type":"webapps","platform":"multiple","port":null,"verified":false,"codes":["CVE-2025-4123"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null}]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 97.1%, higher than 100% of all known CVEs.
