{"schemaVersion":3,"id":"CVE-2025-66308","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"This admin plugin for Grav is an HTML user interface that provides a convenient way to configure Grav and easily create and modify pages. Prior to 1.11.0-beta.1, a Stored Cross-Site Scripting (XSS) vulnerability was identified in the /admin/config/site endpoint of the Grav application. This vulnerability allows attackers to inject malicious scripts into the data[taxonomies] parameter. The injected payload is stored on the server and automatically executed in the browser of any user who accesses the affected site configuration, resulting in a persistent attack vector. This vulnerability is fixed in 1.11.0-beta.1.","dates":{"published":"2025-12-01T22:00:42.343Z","modified":"2025-12-02T16:14:03.036Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.8,"severity":"medium","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":6.8,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":6.8,"severity":"medium","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":5.4,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00214,"percentile":0.11049,"severity":"low","asOf":"2026-10-20T00:00:00.000Z","change":{"pp":0,"baselineDate":"2026-09-20T00:00:00.000Z","baselineScore":0.00214},"history":[{"date":"2026-09-14T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-15T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-16T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-17T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-18T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-19T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-20T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-05T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-06T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-07T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-08T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-09T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-10T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-11T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-12T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-13T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-14T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-20T00:00:00.000Z","score":0.00214,"percentile":0.11049}],"last30":[{"date":"2026-09-20T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-21T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-22T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-23T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-24T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-25T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-26T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-27T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-28T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-29T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-09-30T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-01T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-02T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-03T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-04T00:00:00.000Z","score":0.00214,"percentile":null},{"date":"2026-10-0
