An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4142 in the wild and no public exploit code.\n\nAffected product: eazyserver Sentence To SEO (keywords, description and tags). 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-2026-4142/ (Markdown: https://insights.sbomify.com/CVE-2026-4142/index.md)","id":"CVE-2026-4142","markdown":"https://insights.sbomify.com/CVE-2026-4142/index.md","name":"CVE-2026-4142","record":{"aliases":["GHSA-95vj-cwqx-rpmc"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"high_privilege","summary":"Authenticated administrators can inject arbitrary JavaScript into the plugin settings page via the Permanent keywords field, leading to stored XSS.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Wordfence","cpe":[],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/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":"The Sentence To SEO (keywords, description and tags) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Permanent keywords' field in all versions up to and including 1.0. This is due to insufficient input sanitization and output escaping. The plugin reads user input via filter_input_array(INPUT_POST) which applies no HTML sanitization (FILTER_DEFAULT), stores it unsanitized to the WordPress options table via update_option(), and then outputs the stored value directly into a textarea element without any escaping using PHP short echo tags (\u003c?= ?\u003e). An attacker can break out of the textarea element using a closing \u003c/textarea\u003e tag and inject arbitrary HTML/JavaScript. This makes it possible for authenticated attackers, with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the plugin's settings page.","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 Sentence To SEO (keywords, description and tags)","id":"CVE-2026-4142","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":11,"next":{"headline":"Neos Connector for Fakturama \u003c= 0.0.14 - Cross-Site Request Forgery to Settings Update","id":"CVE-2026-4143"},"packages":[],"prev":{"headline":"Quran Translations \u003c= 1.7 - Cross-Site Request Forgery to Playlist Settings Form","id":"CVE-2026-4141"},"products":["Sentence To SEO (keywords, description and tags)"],"published":"2026-04-22","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-04-22","vendors":["eazyserver"]},"summary":"Authenticated administrators can inject arbitrary JavaScript into the plugin settings page via the Permanent keywords field, leading to stored XSS.","url":"https://insights.sbomify.com/CVE-2026-4142/"}
