Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-24366 exists.\n\nAffected product: Unknown Admin Columns. 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-2021-24366/ (Markdown: https://insights.sbomify.com/CVE-2021-24366/index.md)","id":"CVE-2021-24366","markdown":"https://insights.sbomify.com/CVE-2021-24366/index.md","name":"CVE-2021-24366","record":{"aliases":["GHSA-hrfw-7pg5-g3x6"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"High-privilege users can inject malicious scripts via unsanitized label settings in Admin Columns plugins, enabling stored XSS attacks in multisite environments.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"admin_columns","vendor":"admincolumns"}],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[],"description":"The Admin Columns WordPress plugin before 4.3 and Admin Columns Pro WordPress plugin before 5.5.1 do not sanitise and escape its Label settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup)","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":"Admin Columns Free \u003c 4.3 \u0026 Pro \u003c 5.5.1 - Admin+ Stored XSS in Label","id":"CVE-2021-24366","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"WP Config File Editor \u003c= 1.7.1 - Authenticated Stored Cross-Site Scripting (XSS)","id":"CVE-2021-24367"},"packages":[],"prev":{"headline":"Admin Columns Free (\u003c 4.3.2) \u0026 Pro (\u003c 5.5.2) - Authenticated Stored Cross-Site Scripting (XSS) in Custom Field","id":"CVE-2021-24365"},"products":["Admin Columns","Admin Columns Pro"],"published":"2021-06-21","related":[{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2019-17661","kev_date_added":null,"published":"2019-11-08"},{"cvss_score":5.4,"headline":"Admin Columns Free (\u003c 4.3.2) \u0026 Pro (\u003c 5.5.2) - Authenticated Stored Cross-Site Scripting (XSS) in Custom Field","id":"CVE-2021-24365","kev_date_added":null,"published":"2021-07-12"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-05-05","vendors":["Unknown"]},"summary":"High-privilege users can inject malicious scripts via unsanitized label settings in Admin Columns plugins, enabling stored XSS attacks in multisite environments.","url":"https://insights.sbomify.com/CVE-2021-24366/"}
