An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20865 in the wild and no public exploit code.\n\nAffected product: Delicious Brains Advanced Custom Fields and Advanced Custom Fields Pro. 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-2021-20865/ (Markdown: https://insights.sbomify.com/CVE-2021-20865/index.md)","id":"CVE-2021-20865","markdown":"https://insights.sbomify.com/CVE-2021-20865/index.md","name":"CVE-2021-20865","record":{"aliases":["GHSA-f2fc-p952-6xf6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"An attacker can browse unauthorized database data due to missing authorization checks in the Advanced Custom Fields plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"advanced_custom_fields","vendor":"advancedcustomfields"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Advanced Custom Fields versions prior to 5.11 and Advanced Custom Fields Pro versions prior to 5.11 contain a missing authorization vulnerability in browsing database which may allow a user to browse unauthorized data via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in Advanced Custom Fields and Advanced Custom Fields Pro","id":"CVE-2021-20865","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Missing authorization in Advanced Custom Fields and Advanced Custom Fields Pro","id":"CVE-2021-20866"},"packages":[],"prev":{"headline":"Auth bypass in ELECOM routers","id":"CVE-2021-20864"},"products":["Advanced Custom Fields and Advanced Custom Fields Pro"],"published":"2021-12-13","related":[{"cvss_score":8.8,"headline":"Advanced Custom Fields - Contributor+ PHP Object Injection","id":"CVE-2023-1196","kev_date_added":null,"published":"2023-05-02"},{"cvss_score":8.8,"headline":"Advanced Custom Fields 5.0-5.12.2 - Unauthenticated File Upload","id":"CVE-2022-2594","kev_date_added":null,"published":"2022-08-22"},{"cvss_score":7.5,"headline":"Advanced Custom Fields \u003c 6.3 - Contributor+ Custom Field Access","id":"CVE-2024-4565","kev_date_added":null,"published":"2024-06-20"},{"cvss_score":7.1,"headline":"WordPress Advanced Custom Fields / Advanced Custom Fields PRO plugins \u003c= 6.1.5 vulnerable to Cross Site Scripting (XSS)","id":"CVE-2023-30777","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":6.6,"headline":"Secure Custom Fields \u003c 6.3.6.3 - Admin+ Remote Code Execution","id":"CVE-2024-9529","kev_date_added":null,"published":"2024-11-15"},{"cvss_score":6.5,"headline":"Missing authorization in Advanced Custom Fields","id":"CVE-2022-23183","kev_date_added":null,"published":"2022-03-31"}],"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":["Delicious Brains"]},"summary":"An attacker can browse unauthorized database data due to missing authorization checks in the Advanced Custom Fields plugin.","url":"https://insights.sbomify.com/CVE-2021-20865/"}
