Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-3924 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- getgrav/grav (Packagist): affected all versions up to 1.7.24; no fix listed\n- getgrav/grav (Packagist): affected all versions up to 1.7.24; no fix listed\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-2021-3924/ (Markdown: https://insights.sbomify.com/CVE-2021-3924/index.md)","id":"CVE-2021-3924","markdown":"https://insights.sbomify.com/CVE-2021-3924/index.md","name":"CVE-2021-3924","record":{"aliases":["GHSA-8c5p-4362-9333"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Grav CMS","requires_auth":"low_privilege","summary":"Attackers can exploit a path traversal vulnerability in Grav CMS to read arbitrary files from the server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"grav","vendor":"getgrav"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"grav is vulnerable to Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","ecosystems":["Packagist"],"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":"Path Traversal in getgrav/grav","id":"CVE-2021-3924","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"getgrav:grav","products":["getgrav:grav"],"type":"path_traversal","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2021-3926"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["1.7.24"],"package":"getgrav/grav","purl":null,"source":"GHSA-8c5p-4362-9333"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["1.7.24"],"package":"getgrav/grav","purl":"pkg:composer/getgrav/grav","source":"GHSA-8c5p-4362-9333"}],"prev":{"headline":"Information disclosure in kernel","id":"CVE-2021-3923"},"products":["getgrav/grav"],"published":"2021-11-05","related":[{"cvss_score":10,"headline":"Grav Server Side Template Injection vulnerability","id":"CVE-2023-34251","kev_date_added":null,"published":"2023-06-14"},{"cvss_score":9.8,"headline":"Cross-site scripting in n/a","id":"CVE-2025-46199","kev_date_added":null,"published":"2025-07-25"},{"cvss_score":9.3,"headline":"GravCMS 1.10.7 - Arbitrary YAML Write/Update (Unauthenticated) (2)","id":"CVE-2021-47812","kev_date_added":null,"published":"2026-01-15"},{"cvss_score":9.1,"headline":"Grav may be vulnerable to SSRF attack via Twig Templates","id":"CVE-2025-66844","kev_date_added":null,"published":"2025-12-15"},{"cvss_score":9.1,"headline":"Code Injection in getgrav/grav","id":"CVE-2022-2073","kev_date_added":null,"published":"2022-06-29"},{"cvss_score":8.9,"headline":"Grav: Stored XSS via Tag Injection","id":"CVE-2026-42611","kev_date_added":null,"published":"2026-05-11"},{"cvss_score":8.8,"headline":"Grav: Unauthenticated Path Traversal \u0026 Arbitrary File Write in FormFlash component.","id":"CVE-2026-42608","kev_date_added":null,"published":"2026-05-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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 a path traversal vulnerability in Grav CMS to read arbitrary files from the server.","url":"https://insights.sbomify.com/CVE-2021-3924/"}
