{"id":"CVE-2026-42611","summary":"Grav: Stored XSS via Tag Injection","details":"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.","aliases":["GHSA-w8cg-7jcj-4vv2"],"modified":"2026-07-15T01:49:21.839137685Z","published":"2026-05-11T15:20:47.890Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42611.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-79"]},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getgrav/grav","events":[{"introduced":"0"},{"fixed":"5a12f9be8314682c8713e569e330f11805d0a663"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.0.0-beta.2"}]}}],"versions":["2.0.0-beta.1","1.8.0-beta.29","1.8.0-beta.28","1.8.0-beta.27","1.8.0-beta.26","1.8.0-beta.25","1.8.0-beta.24","1.8.0-beta.23","1.8.0-beta.22","1.8.0-beta.21","1.8.0-beta.20","1.8.0-beta.19","1.8.0-beta.18","1.8.0-beta.17","1.8.0-beta.16","1.8.0-beta.15","1.8.0-beta.14","1.8.0-beta.13","1.8.0-beta.12","1.8.0-beta.11","1.8.0-beta.10","1.8.0-beta.9","1.8.0-beta.8","1.8.0-beta.7","1.8.0-beta.6","1.8.0-beta.5","1.8.0-beta.4","1.8.0-beta.3","1.8.0-beta.2","1.8.0-beta.1","1.7.0-rc.20","1.7.0-rc.19","1.7.0-rc.18","1.7.0-rc.17","1.7.0-rc.15","1.7.0-rc.14","1.7.0-rc.13","1.7.0-rc.12","1.7.0-rc.10","1.7.0-rc.9","1.7.0-rc.8","1.7.0-rc.7","1.7.0-rc.6","1.7.0-rc.5","1.7.0-rc.4","1.7.0-rc.3","1.7.0-rc.2","1.7.0-rc.1","1.7.0-beta.10","1.7.0-beta.9","1.7.0-beta.8","1.7.0-beta.7","1.7.0-beta.6","1.7.0-beta.5","1.7.0-beta.4","1.7.0-beta.3","1.7.0-beta.2","1.7.0-beta.1","1.6.0-rc.4","1.6.0-rc.3","1.6.0-rc.2","1.6.0-rc.1","1.6.0-beta.8","1.6.0-beta.7","1.6.0-beta.6","1.6.0-beta.5","1.6.0-beta.2","1.6.0-beta.1","1.5.0-rc.1","1.5.0-beta.2","1.5.0-beta.1","1.3.0-rc.5","1.3.0-rc.4","1.3.0-rc.3","1.3.0-rc.1","1.2.0-rc.3","1.2.0-rc.2","1.2.0-rc.1","1.1.9-rc.3","1.1.9-rc.2","1.1.9-rc.1","1.1.0-rc.3","1.1.0-rc.2","1.1.0-rc.1","1.1.0-beta.5","1.1.0-beta.4","1.1.0-beta.3","1.1.0-beta.2","1.1.0-beta.1","0.9.19","0.9.18","0.9.17","0.9.16","0.9.15","0.9.14","0.9.13","0.9.12","0.9.11","0.9.10","0.9.9","0.9.8","0.9.7","0.9.6","0.9.5","0.9.4","0.9.3","0.9.2","0.9.0","0.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42611.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:H"}]}
