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-2021-36572 exists.\n\nAffected packages and fixed versions:\n- feehi/feehicms (Packagist): affected all versions up to 2.1.1; no fix listed\n- feehi/feehicms (Packagist): affected all versions up to 2.1.1; no fix listed\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-2021-36572/ (Markdown: https://insights.sbomify.com/CVE-2021-36572/index.md)","id":"CVE-2021-36572","markdown":"https://insights.sbomify.com/CVE-2021-36572/index.md","name":"CVE-2021-36572","record":{"aliases":["GHSA-m54v-gv8p-9pqp"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Feehi CMS","requires_auth":"none","summary":"Attackers can execute arbitrary code via XSS in the login page username field of Feehi CMS.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"feehicms","vendor":"feehi"}],"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-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Cross Site Scripting (XSS) vulnerability in Feehi CMS thru 2.1.1 allows attackers to run arbitrary code via the user name field of the login page.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"FeehiCMS Cross Site Scripting vulnerability","id":"CVE-2021-36572","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"FeehiCMS Unrestricted Upload vulnerability","id":"CVE-2021-36573"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["2.1.1"],"package":"feehi/feehicms","purl":null,"source":"GHSA-m54v-gv8p-9pqp"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["2.1.1"],"package":"feehi/feehicms","purl":"pkg:composer/feehi/feehicms","source":"GHSA-m54v-gv8p-9pqp"}],"prev":{"headline":"Cross-site request forgery in n/a","id":"CVE-2021-36570"},"products":["n/a"],"published":"2022-12-15","related":[{"cvss_score":9.8,"headline":"liufee CMS File Upload vulnerability","id":"CVE-2020-21174","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"Liufee CMS File Upload vulnerability","id":"CVE-2020-21489","kev_date_added":null,"published":"2023-06-20"},{"cvss_score":9.8,"headline":"FeehiCMS has an arbitrary file upload vulnerability","id":"CVE-2020-21516","kev_date_added":null,"published":"2022-09-06"},{"cvss_score":9.8,"headline":"Arbitrary Code Execution in feehi/cms","id":"CVE-2020-21322","kev_date_added":null,"published":"2021-09-15"},{"cvss_score":6.9,"headline":"FeehiCMS TimThumb timthumb.php server-side request forgery","id":"CVE-2025-15264","kev_date_added":null,"published":"2025-12-30"},{"cvss_score":6.5,"headline":"FeehiCMS Has a Remote Code Execution via Unrestricted File Upload in Ad Management","id":"CVE-2025-65657","kev_date_added":null,"published":"2025-12-02"},{"cvss_score":6.5,"headline":"FeehiCMS fails to enforce server-side immutability","id":"CVE-2025-63523","kev_date_added":null,"published":"2025-12-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2025-04-21","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code via XSS in the login page username field of Feehi CMS.","url":"https://insights.sbomify.com/CVE-2021-36572/"}
