Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-100670 exists.\n\nAffected product: getgrav grav. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-100670/ (Markdown: https://insights.sbomify.com/CVE-2026-100670/index.md)","id":"CVE-2026-100670","markdown":"https://insights.sbomify.com/CVE-2026-100670/index.md","name":"CVE-2026-100670","record":{"aliases":["GHSA-mwjj-r7vm-pgqm","GHSA-xw59-q7ph-pgh5"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS","requires_auth":"low_privilege","summary":"Authenticated backend operators can escalate to super-admin by bypassing blueprint guards via dot-notation keys, gaining full control.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"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.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Grav CMS 2.0.14 through 2.0.24 Privilege Escalation via Blueprint Guard Bypass","id":"CVE-2026-100670","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Grav before 2.0.25 Session Cookie Theft via Twig Sandbox","id":"CVE-2026-100671"},"packages":[],"prev":{"headline":"Grav before 2.0.25 Sensitive File Disclosure via Case-Variation Bypass","id":"CVE-2026-100669"},"products":["grav"],"published":"2026-09-26","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["getgrav"]},"summary":"Authenticated backend operators can escalate to super-admin by bypassing blueprint guards via dot-notation keys, gaining full control.","url":"https://insights.sbomify.com/CVE-2026-100670/"}
