An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-4227 exists.\n\nAffected product: Unknown ark-commenteditor. 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-2021-4227/ (Markdown: https://insights.sbomify.com/CVE-2021-4227/index.md)","id":"CVE-2021-4227","markdown":"https://insights.sbomify.com/CVE-2021-4227/index.md","name":"CVE-2021-4227","record":{"aliases":["GHSA-h3w7-w9rh-w829"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Attackers can inject iframes into comments via the source editor, loading arbitrary content and potentially executing scripts in the victim's browser.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"WPScan","cpe":[{"product":"ark_wysiwyg_comment_editor","vendor":"obg"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"The ark-commenteditor WordPress plugin through 2.15.6 does not properly sanitise or encode the comments when in Source editor, allowing attackers to inject an iFrame in the page and thus load arbitrary content from any page to the comment section","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":"Ark Comment Editor \u003c= 2.15.6 - Iframe Injection via Comment","id":"CVE-2021-4227","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Hard-coded TLS Certificate","id":"CVE-2021-4228"},"packages":[],"prev":{"headline":"RSFirewall \u003c 1.1.25 - IP Block Bypass","id":"CVE-2021-4226"},"products":["ark-commenteditor"],"published":"2024-01-16","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-06-02","vendors":["Unknown"]},"summary":"Attackers can inject iframes into comments via the source editor, loading arbitrary content and potentially executing scripts in the victim's browser.","url":"https://insights.sbomify.com/CVE-2021-4227/"}
