An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-36839 in the wild and no public exploit code.\n\nAffected product: Space X-Chimp Social Media Follow Buttons Bar (WordPress plugin). 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-2021-36839/ (Markdown: https://insights.sbomify.com/CVE-2021-36839/index.md)","id":"CVE-2021-36839","markdown":"https://insights.sbomify.com/CVE-2021-36839/index.md","name":"CVE-2021-36839","record":{"aliases":["GHSA-pjp7-ffv7-qj9m"],"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":"high_privilege","summary":"Authenticated administrators can inject malicious scripts into the Social Media Follow Buttons Bar plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"social_media_follow_buttons_bar","vendor":"spacexchimp"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/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":"Authenticated (admin+) Stored Cross-Site Scripting (XSS) vulnerability in Social Media Follow Buttons Bar plugin \u003c= 4.73 at WordPress.","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":"Cross-site scripting in Social Media Follow Buttons Bar (WordPress plugin)","id":"CVE-2021-36839","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"YITH Maintenance Mode (WordPress plugin) \u003c= 1.3.7 - Authenticated Stored Cross-Site Scripting (XSS) vulnerability.","id":"CVE-2021-36841"},"packages":[],"prev":{"headline":"WordPress MC4WP plugin \u003c= 4.8.6 - Authenticated Stored Cross-Site Scripting (XSS) vulnerability","id":"CVE-2021-36833"},"products":["Social Media Follow Buttons Bar (WordPress plugin)"],"published":"2022-09-30","related":[],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-28","vendors":["Space X-Chimp"]},"summary":"Authenticated administrators can inject malicious scripts into the Social Media Follow Buttons Bar plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-36839/"}
