{"schema":"threatline.record/2","record":{"id":"CVE-2026-100670","aliases":["GHSA-mwjj-r7vm-pgqm"],"summary":"Grav CMS 2.0.14 through 2.0.24 Privilege Escalation via Blueprint Guard Bypass","details":"Grav CMS 2.0.14 through 2.0.24 contains a privilege escalation vulnerability in the group and account blueprints. The access map is gated by a `security@: admin.super` guard that is resolved by the field's exact path, so a submitted flat dot-notation key such as `access.admin.super` (instead of the nested `access[admin][super]`) matches no blueprint rule, survives BlueprintSchema::filterArray() and flattening, and is written by FlexObject::update() via setNestedProperty(), which splits on `.` and reconstructs the nested value. An authenticated backend operator using the flex accounts backend who holds admin.users but not admin.super can therefore grant admin.super to their own account or to a group they belong to and escalate to full super-admin, gaining control over configuration, plugin and theme installation, the file manager, and all accounts. Fixed in 2.0.25, which drops any dotted key whose ancestor path is disabled or marked validate.ignore.","categories":["Unclassified"],"product":"grav","vendor":"getgrav","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100670","source_modified_at":"2026-09-30T14:57:47.995Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"grav","vendor":"getgrav","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"2.0.25"},{"version":"2.0.25","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100670","source_modified_at":"2026-09-30T14:57:47.995Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"grav","ecosystem":null},"version":"2.0.25","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00303,"percentile":0.21905,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:23:34.756Z","modified_at":"2026-09-30T14:57:47.995Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100670","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T14:57:47.995Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100670","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/getgrav/grav/security/advisories/GHSA-mwjj-r7vm-pgqm","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/grav-cms-2.0.14-through-2.0.24-privilege-escalation-via-blueprint-guard-bypass","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-09-30T14:57:11.982511Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T14:57:47.995Z","content_hash":"5855dc2d7481c64287691485d9a8dcce8fcf2db5871a14c5ab8cddbdbc626419"}}
