An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-36851 in the wild and no public exploit code.\n\nAffected product: Web-Settler Testimonial Slider – Free Testimonials Slider Plugin (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-2021-36851/ (Markdown: https://insights.sbomify.com/CVE-2021-36851/index.md)","id":"CVE-2021-36851","markdown":"https://insights.sbomify.com/CVE-2021-36851/index.md","name":"CVE-2021-36851","record":{"aliases":["GHSA-rjq3-c2jr-r9rq"],"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 attackers can inject malicious scripts via color parameters in the Testimonial Slider plugin, potentially compromising user sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"testimonial_slider","vendor":"web-settler"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/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 (editor or higher user role) Cross-Site Scripting (XSS) vulnerability in Web-Settler Testimonial Slider – Free Testimonials Slider Plugin (WordPress plugin) via parameters mpsp_posts_bg_color, mpsp_posts_description_color, mpsp_slide_nav_button_color.","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 Testimonial Slider plugin \u003c= 3.5.8.3 - Cross-Site Scripting (XSS) vulnerability","id":"CVE-2021-36851","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 WP Hotel Booking plugin \u003c= 1.10.5 - Cross-Site Request Forgery (CSRF) vulnerability","id":"CVE-2021-36852"},"packages":[],"prev":{"headline":"WordPress Media File Renamer – Auto \u0026 Manual Rename plugin \u003c= 5.1.9 - Cross-Site Request Forgery (CSRF) vulnerability","id":"CVE-2021-36850"},"products":["Testimonial Slider – Free Testimonials Slider Plugin (WordPress plugin)"],"published":"2022-04-04","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":["Web-Settler"]},"summary":"Authenticated attackers can inject malicious scripts via color parameters in the Testimonial Slider plugin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2021-36851/"}
