{"identifier":"CVE-2026-42611","cve":{"id":"CVE-2026-42611","description":"Grav is a file-based Web platform. 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":"2026-05-11T16:17:34.173000+00:00","modified":"2026-10-26T18:10:00.173000+00:00","status":"Analyzed","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","cvss_version":"3.1","affected":[{"criteria":"cpe:2.3:a:getgrav:grav:*:*:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"1.8.0","versionEndExcluding":""},{"criteria":"cpe:2.3:a:getgrav:grav:2.0.0:beta1:*:*:*:*:*:*","versionStartIncluding":"","versionStartExcluding":"","versionEndIncluding":"","versionEndExcluding":""}],"weaknesses":["CWE-79"],"references":[{"url":"https://github.com/getgrav/grav/commit/5a12f9be8314682c8713e569e330f11805d0a663","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-w8cg-7jcj-4vv2","source":"security-advisories@github.com","tags":["Exploit","Patch","Vendor Advisory"]},{"url":"https://github.com/getgrav/grav/security/advisories/GHSA-w8cg-7jcj-4vv2","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Patch","Vendor Advisory"]}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:H","baseScore":8.9,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"LOW","availabilityImpact":"HIGH"},"exploitabilityScore":2.3,"impactScore":6.0}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-05-11T18:23:37.346111Z","id":"CVE-2026-42611","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:getgrav:grav:*:*:*:*:*:*:*:*","versionEndIncluding":"1.8.0","matchCriteriaId":"9C284702-7909-4A5C-91FE-392FC5BA58C7"},{"vulnerable":true,"criteria":"cpe:2.3:a:getgrav:grav:2.0.0:beta1:*:*:*:*:*:*","matchCriteriaId":"1ABB323F-20AF-40F3-BCD9-262644D242A1"}]}]}],"source":"nvd","retrieved_at":"2026-10-28T10:24:32.321967+00:00","exploited":false,"kev_stale":false,"products":["getgrav / grav"],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.003,"percentile":0.22703,"date":"2026-10-28","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/getgrav/grav/commit/5a12f9be8314682c8713e569e330f11805d0a663","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-42611","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-42611","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-42611","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
