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-2021-36899 in the wild and no public exploit code.\n\nAffected product: Gabe Livan Asset CleanUp: Page Speed Booster (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-2021-36899/ (Markdown: https://insights.sbomify.com/CVE-2021-36899/index.md)","id":"CVE-2021-36899","markdown":"https://insights.sbomify.com/CVE-2021-36899/index.md","name":"CVE-2021-36899","record":{"aliases":["GHSA-q34g-xwpj-xqx4"],"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 via reflected XSS in the Asset CleanUp plugin, potentially compromising user sessions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[{"product":"_page_speed_booster_project","vendor":"asset_cleanup\\"}],"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+) Reflected Cross-Site Scripting (XSS) vulnerability in Gabe Livan's Asset CleanUp: Page Speed Booster plugin \u003c= 1.3.8.4 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 Asset CleanUp: Page Speed Booster (WordPress plugin)","id":"CVE-2021-36899","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 Age Gate plugin \u003c= 2.17.0 - Unauthenticated Stored Cross-Site Scripting (XSS) vulnerability","id":"CVE-2021-36901"},"packages":[],"prev":{"headline":"WordPress Quiz And Survey Master plugin \u003c= 7.3.4 - Auth.
