An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-23439 in the wild and no public exploit code.\n\nAffected product: willshouse TinyMCE Extended Config. 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-2025-23439/ (Markdown: https://insights.sbomify.com/CVE-2025-23439/index.md)","id":"CVE-2025-23439","markdown":"https://insights.sbomify.com/CVE-2025-23439/index.md","name":"CVE-2025-23439","record":{"aliases":["GHSA-2739-vvgg-6rwf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WordPress plugin","requires_auth":"none","summary":"Reflected XSS in TinyMCE Extended Config allows attackers to execute arbitrary scripts in victim browsers via crafted URLs.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Patchstack","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in willshouse TinyMCE Extended Config tinymce-extended-config allows Reflected XSS.This issue affects TinyMCE Extended Config: from n/a through \u003c= 0.1.0.","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":"WordPress TinyMCE Extended Config plugin \u003c= 0.1.0 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23439","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"WordPress radSLIDE plugin \u003c= 2.1 - Broken Access Control to Stored Cross-Site Scripting vulnerability","id":"CVE-2025-23440"},"packages":[],"prev":{"headline":"WordPress WP PT-Viewer plugin \u003c= 2.0.2 - Reflected XSS vulnerability","id":"CVE-2025-23438"},"products":["TinyMCE Extended Config"],"published":"2025-03-03","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":"total"},"state":"PUBLISHED","updated":"2026-05-12","vendors":["willshouse"]},"summary":"Reflected XSS in TinyMCE Extended Config allows attackers to execute arbitrary scripts in victim browsers via crafted URLs.","url":"https://insights.sbomify.com/CVE-2025-23439/"}
