An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-24870 exists.\n\nAffected product: Unknown WP Fastest Cache. 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-2021-24870/ (Markdown: https://insights.sbomify.com/CVE-2021-24870/index.md)","id":"CVE-2021-24870","markdown":"https://insights.sbomify.com/CVE-2021-24870/index.md","name":"CVE-2021-24870","record":{"aliases":["GHSA-mvrw-4465-r2jc"],"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":"none","summary":"Attackers can inject malicious scripts via CSRF in WP Fastest Cache, potentially compromising high-privilege user accounts.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"wp_fastest_cache","vendor":"wpfastestcache"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"The WP Fastest Cache WordPress plugin before 0.9.5 is lacking a CSRF check in its wpfc_save_cdn_integration AJAX action, and does not sanitise and escape some the options available via the action, which could allow attackers to make logged in high privilege users call it and set a Cross-Site Scripting payload","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"WP Fastest Cache \u003c 0.9.5 - CSRF to Stored Cross-Site Scripting","id":"CVE-2021-24870","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Get Custom Field Values \u003c 4.0.1 - Contributor+ Stored Cross-Site Scripting","id":"CVE-2021-24871"},"packages":[],"prev":{"headline":"WP Fastest Cache \u003c 0.9.5 - Subscriber+ SQL Injection","id":"CVE-2021-24869"},"products":["WP Fastest Cache"],"published":"2024-01-16","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2015-9316","kev_date_added":null,"published":"2019-08-14"},{"cvss_score":9.1,"headline":"Path traversal in n/a","id":"CVE-2019-13635","kev_date_added":null,"published":"2019-07-30"},{"cvss_score":8.8,"headline":"WP Fastest Cache \u003c 0.9.5 - Subscriber+ SQL Injection","id":"CVE-2021-24869","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":8.8,"headline":"WP Fatest Cache \u003c 1.1.5 - Blind SSRF via CSRF","id":"CVE-2023-1938","kev_date_added":null,"published":"2023-05-30"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2018-17584","kev_date_added":null,"published":"2019-04-15"},{"cvss_score":8.8,"headline":"Cross-site request forgery in n/a","id":"CVE-2015-4089","kev_date_added":null,"published":"2017-09-19"},{"cvss_score":8,"headline":"WP Fastest Cache \u003c= 0.9.0.2 - Authenticated (Subscriber+) Arbitrary File Deletion","id":"CVE-2020-36836","kev_date_added":null,"published":"2024-10-16"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-09","vendors":["Unknown"]},"summary":"Attackers can inject malicious scripts via CSRF in WP Fastest Cache, potentially compromising high-privilege user accounts.","url":"https://insights.sbomify.com/CVE-2021-24870/"}
