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-2021-24656 in the wild and no public exploit code.\n\nAffected product: Unknown Simple Social Media Share Buttons – Social Sharing for Everyone. 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-2021-24656/ (Markdown: https://insights.sbomify.com/CVE-2021-24656/index.md)","id":"CVE-2021-24656","markdown":"https://insights.sbomify.com/CVE-2021-24656/index.md","name":"CVE-2021-24656","record":{"aliases":["GHSA-jr4w-g4rp-m3m8"],"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":"High-privilege users can inject malicious scripts via Share Title settings, leading to stored XSS attacks on frontend pages.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"simple_social_buttons","vendor":"wpbrigade"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","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":"The Simple Social Media Share Buttons WordPress plugin before 3.2.4 does not escape the Share Title settings before outputting it in the frontend pages or posts (depending on the settings used), allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.","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":"Simple Social Media Share Buttons \u003c 3.2.4 - Authenticated Stored Cross-Site Scripting","id":"CVE-2021-24656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Limit Login Attempts \u003c 4.0.50 - Unauthenticated Stored Cross-Site Scripting","id":"CVE-2021-24657"},"packages":[],"prev":{"headline":"WP User Manager \u003c 2.6.3 - Arbitrary User Password Reset to Account Compromise","id":"CVE-2021-24655"},"products":["Simple Social Media Share Buttons – Social Sharing for Everyone"],"published":"2021-10-11","related":[{"cvss_score":5.3,"headline":"Simple Social Buttons \u003c 5.1.1 - Unauthenticated Password Protected Post Access","id":"CVE-2023-5845","kev_date_added":null,"published":"2023-11-27"},{"cvss_score":4.8,"headline":"Simple Social Media Share Buttons \u003c 6.0.0 - Admin+ Stored XSS","id":"CVE-2024-13610","kev_date_added":null,"published":"2025-04-15"}],"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":"High-privilege users can inject malicious scripts via Share Title settings, leading to stored XSS attacks on frontend pages.","url":"https://insights.sbomify.com/CVE-2021-24656/"}
