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-2021-36849 in the wild and no public exploit code.\n\nAffected product: René Hermenau Social Media Share Buttons | MashShare (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-2021-36849/ (Markdown: https://insights.sbomify.com/CVE-2021-36849/index.md)","id":"CVE-2021-36849","markdown":"https://insights.sbomify.com/CVE-2021-36849/index.md","name":"CVE-2021-36849","record":{"aliases":["GHSA-h6g6-h7qh-75h9"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"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 Share Buttons plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"social_media_share_buttons","vendor":"social_media_share_buttons_project"}],"cvss":{"score":3.4,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:N/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 René Hermenau's Social Media Share Buttons plugin \u003c= 3.8.1 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":"WordPress Social Media Share Buttons plugin \u003c= 3.8.1 - Authenticated Stored Cross-Site Scripting (XSS) vulnerability","id":"CVE-2021-36849","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"WordPress Media File Renamer – Auto \u0026 Manual Rename plugin \u003c= 5.1.9 - Cross-Site Request Forgery (CSRF) vulnerability","id":"CVE-2021-36850"},"packages":[],"prev":{"headline":"WordPress Social Media Feather plugin \u003c= 2.0.4 - Authenticated Stored Cross-Site Scripting (XSS) vulnerability","id":"CVE-2021-36848"},"products":["Social Media Share Buttons | MashShare (WordPress plugin)"],"published":"2022-07-20","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":["René Hermenau"]},"summary":"Authenticated administrators can inject malicious scripts into the Social Media Share Buttons plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-36849/"}
