Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-24807 in the wild and no public exploit code.\n\nAffected product: Unknown Support Board. 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-2021-24807/ (Markdown: https://insights.sbomify.com/CVE-2021-24807/index.md)","id":"CVE-2021-24807","markdown":"https://insights.sbomify.com/CVE-2021-24807/index.md","name":"CVE-2021-24807","record":{"aliases":["GHSA-g623-mj4w-fprv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"low_privilege","summary":"Authenticated agents can inject malicious scripts via the notes field, leading to XSS execution for administrators and other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"support_board","vendor":"schiocco"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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 Support Board WordPress plugin before 3.3.5 allows Authenticated (Agent+) users to perform Cross-Site Scripting attacks by placing a payload in the notes field, when an administrator or any authenticated user go to the chat the XSS will be automatically executed.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2021-10-07","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2021-10-07T10:13:10Z","kind":"github_poc","ref":"https://github.com/dldygnl/CVE-2021-24807","stars":1,"title":"Support Board 3.3.4 Authenticated Stored XSS"}],"tier":"poc_unverified"},"has_fix":null,"headline":"Support Board \u003c 3.3.5 - Agent+ Stored Cross-Site Scripting","id":"CVE-2021-24807","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":3,"next":{"headline":"BP Better Messages \u003c 1.9.9.41 - Reflected Cross-Site Scripting","id":"CVE-2021-24808"},"packages":[],"prev":{"headline":"wpDiscuz \u003c 7.3.4 - Arbitrary Comment Addition/Edition/Deletion via CSRF","id":"CVE-2021-24806"},"products":["Support Board"],"published":"2021-11-08","related":[{"cvss_score":9.8,"headline":"Support Board \u003c= 3.8.0 - Unauthenticated Arbitrary File Deletion","id":"CVE-2025-4828","kev_date_added":null,"published":"2025-07-08"},{"cvss_score":9.8,"headline":"Support Board \u003c= 3.8.0 - Unauthenticated Authorization Bypass due to Use of Default Secret Key","id":"CVE-2025-4855","kev_date_added":null,"published":"2025-07-08"},{"cvss_score":8.7,"headline":"SQL Injection vulnerability in Support Board","id":"CVE-2026-4815","kev_date_added":null,"published":"2026-03-25"},{"cvss_score":8.1,"headline":"Support Board \u003c 3.3.6 - Arbitrary File Deletion via CSRF","id":"CVE-2021-24823","kev_date_added":null,"published":"2022-02-28"},{"cvss_score":4.8,"headline":"Reflected Cross Site Scripting (XSS) vulnerability in Support Board","id":"CVE-2026-4816","kev_date_added":null,"published":"2026-03-25"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["Unknown"]},"summary":"Authenticated agents can inject malicious scripts via the notes field, leading to XSS execution for administrators and other users.","url":"https://insights.sbomify.com/CVE-2021-24807/"}
