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-2025-23490 in the wild and no public exploit code.\n\nAffected product: Michael Stursberg Browser-Update-Notify. 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-2025-23490/ (Markdown: https://insights.sbomify.com/CVE-2025-23490/index.md)","id":"CVE-2025-23490","markdown":"https://insights.sbomify.com/CVE-2025-23490/index.md","name":"CVE-2025-23490","record":{"aliases":["GHSA-8wxr-c457-gcq8"],"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":"An attacker can execute arbitrary scripts in the context of other users' browsers via reflected XSS in the Browser-Update-Notify plugin.","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 Michael Stursberg Browser-Update-Notify browser-update-notify allows Reflected XSS.This issue affects Browser-Update-Notify: from n/a through \u003c= 0.2.1.","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 Browser-Update-Notify plugin \u003c= 0.2.1 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23490","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 VSTEMPLATE Creator plugin \u003c= 2.0.2 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23491"},"packages":[],"prev":{"headline":"WordPress WP-Announcements plugin \u003c= 1.8 - Reflected Cross Site Scripting (XSS) vulnerability","id":"CVE-2025-23489"},"products":["Browser-Update-Notify"],"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":"2026-04-28","vendors":["Michael Stursberg"]},"summary":"An attacker can execute arbitrary scripts in the context of other users' browsers via reflected XSS in the Browser-Update-Notify plugin.","url":"https://insights.sbomify.com/CVE-2025-23490/"}
