An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-24241 in the wild and no public exploit code.\n\nAffected product: Unknown 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-2021-24241/ (Markdown: https://insights.sbomify.com/CVE-2021-24241/index.md)","id":"CVE-2021-24241","markdown":"https://insights.sbomify.com/CVE-2021-24241/index.md","name":"CVE-2021-24241","record":{"aliases":["GHSA-qrc3-2vgc-v73w"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can execute arbitrary scripts in the context of other users via a reflected XSS vulnerability in the Advanced Custom Fields Pro update settings page.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"advanced_custom_fields","vendor":"advancedcustomfields"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Advanced Custom Fields Pro WordPress plugin before 5.9.1 did not properly escape the generated update URL when outputting it in an attribute, leading to a reflected Cross-Site Scripting issue in the update settings page.","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":"Advanced Custom Field Pro \u003c 5.9.1 - Reflected Cross-Site Scripting (XSS)","id":"CVE-2021-24241","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"Tutor LMS \u003c 1.8.8 - Authenticated Local File Inclusion","id":"CVE-2021-24242"},"packages":[],"prev":{"headline":"Business Hours Pro \u003c= 5.5.0 - Unauthenticated Arbitrary File Upload to RCE","id":"CVE-2021-24240"},"products":["Advanced Custom Fields Pro"],"published":"2021-04-22","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":7.5,"headline":"Missing authorization in Advanced Custom Fields and Advanced Custom Fields Pro","id":"CVE-2021-20865","kev_date_added":null,"published":"2021-12-13"},{"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":["Unknown"]},"summary":"Attackers can execute arbitrary scripts in the context of other users via a reflected XSS vulnerability in the Advanced Custom Fields Pro update settings page.","url":"https://insights.sbomify.com/CVE-2021-24241/"}
