{"schemaVersion":3,"id":"CVE-2025-11539","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Grafana Image Renderer is vulnerable to remote code execution due to an arbitrary file write vulnerability. This is due to the fact that the /render/csv endpoint lacked validation of the filePath parameter that allowed an attacker to save a shared object to an arbitrary location that is then loaded by the Chromium process.\n\nInstances are vulnerable if:\n\n1. The default token (\"authToken\") is not changed, or is known to the attacker.\n2. The attacker can reach the image renderer endpoint.\nThis issue affects grafana-image-renderer: from 1.0.0 through 4.0.16.","dates":{"published":"2025-10-09T07:18:15.819Z","modified":"2026-02-26T17:47:59.419Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":9.9,"severity":"critical","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":9.9,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":9.9,"severity":"critical","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00636,"percentile":0.49799,"severity":"low","asOf":"2026-10-21T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-21T00:00:00.000Z","baselineScore":0.00636},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-21T00:00:00.000Z","score":0.00636,"percentile":0.49799}],"last30":[{"date":"2026-09-21T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00636,"percentile":null},{"date":"2026-10-10T00:00:00.000Z
