Prior to 2.0.0-beta.2, a low-privileged (with the ability to create a page) user can cause XSS with the injection of svg element. The XSS can further be escalated to dump the entire system information available under /admin/config/info whenever a Super Admin visits the page; which can further be chained with the use of admin-nonce to do a complete server compromise (RCE). This vulnerability is fixed in 2.0.0-beta.2.","published":"2026-05-11T15:20:47.890Z","modified":"2026-08-07T11:50:18.476402495Z","cvss":{"score":8.9,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:H"},"epss":{"score":0.003,"percentile":0.22319,"asOf":"2026-08-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"getgrav/grav","fixedVersion":"2.0.0-beta.2"}],"fix":{"url":"https://github.com/getgrav/grav/commit/5a12f9be8314682c8713e569e330f11805d0a663","label":"getgrav/grav@5a12f9b"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42611.json"},{"type":"ADVISORY","url":"https://github.com/getgrav/grav/security/advisories/GHSA-w8cg-7jcj-4vv2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42611"},{"type":"FIX","url":"https://github.com/getgrav/grav/commit/5a12f9be8314682c8713e569e330f11805d0a663"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:18.476402495Z"}}
