Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3799 in the wild and no public exploit code.\n\nAffected product: getgrav/grav-plugin-admin. 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-2021-3799/ (Markdown: https://insights.sbomify.com/CVE-2021-3799/index.md)","id":"CVE-2021-3799","markdown":"https://insights.sbomify.com/CVE-2021-3799/index.md","name":"CVE-2021-3799","record":{"aliases":["GHSA-vxv9-wpm2-64cm"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS admin plugin","requires_auth":"low_privilege","summary":"Attackers can exploit improper UI layer restrictions in the Grav admin plugin to bypass security controls or perform clickjacking attacks.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"grav-plugin-admin","vendor":"getgrav"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-1021","name":"Improper Restriction of Rendered UI Layers or Frames"}],"description":"grav-plugin-admin is vulnerable to Improper Restriction of Rendered UI Layers or Frames","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Improper Restriction of Rendered UI Layers or Frames in getgrav/grav-plugin-admin","id":"CVE-2021-3799","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"other","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Information disclosure in Glib","id":"CVE-2021-3800"},"packages":[],"prev":{"headline":"Information disclosure in opencryptoki","id":"CVE-2021-3798"},"products":["getgrav/grav-plugin-admin"],"published":"2021-09-27","related":[{"cvss_score":9.3,"headline":"Unauthenticated Arbitrary YAML Write/Update leads to Code Execution","id":"CVE-2021-21425","kev_date_added":null,"published":"2021-04-07"},{"cvss_score":6.8,"headline":"Grav Admin Plugin vulnerable to Cross-Site Scripting (XSS) Stored endpoint `/admin/config/site` parameter `data[taxonomies]`","id":"CVE-2025-66308","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":6.5,"headline":"Grav Admin Plugin vulnerable to User Enumeration \u0026 Email Disclosure","id":"CVE-2025-66307","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":6.2,"headline":"Grav is vulnerable to Cross-Site Scripting (XSS) Reflected endpoint /admin/pages/[page], parameter data[header][content][items], located in the \"Blog Config\" tab","id":"CVE-2025-66309","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":6.2,"headline":"Grav vulnerable to Cross-Site Scripting (XSS) Stored endpoint `/admin/pages/[page]` parameter `data[header][template]` in Advanced Tab","id":"CVE-2025-66310","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":6.2,"headline":"Grav vulnerable to Cross-Site Scripting (XSS) Stored endpoint `/admin/pages/[page]` in Multiples parameters","id":"CVE-2025-66311","kev_date_added":null,"published":"2025-12-01"},{"cvss_score":6.2,"headline":"Grav Admin Plugin is vulnerable to Cross-Site Scripting (XSS) Stored endpoint `/admin/accounts/groups/[group]` parameter `data[readableName]`","id":"CVE-2025-66312","kev_date_added":null,"published":"2025-12-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["getgrav"]},"summary":"Attackers can exploit improper UI layer restrictions in the Grav admin plugin to bypass security controls or perform clickjacking attacks.","url":"https://insights.sbomify.com/CVE-2021-3799/"}
