Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-53478 in the wild and no public exploit code.\n\nAffected product: Wikimedia Foundation Mediawiki - CheckUser extension. 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-2025-53478/ (Markdown: https://insights.sbomify.com/CVE-2025-53478/index.md)","id":"CVE-2025-53478","markdown":"https://insights.sbomify.com/CVE-2025-53478/index.md","name":"CVE-2025-53478","record":{"aliases":["GHSA-r979-wmj9-cr9m"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki CheckUser extension","requires_auth":"low_privilege","summary":"Reflected XSS in MediaWiki CheckUser extension allows attackers to execute scripts via unsanitized i18n messages on the Investigate page.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/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":"The CheckUser extension’s Special:Investigate interface is vulnerable to reflected XSS due to improper escaping of certain internationalized system messages rendered on the “IPs and User agents” tab.\n\nThis issue affects Mediawiki - CheckUser extension: from 1.39.X before 1.39.13, from 1.42.X before 1.42.7, from 1.43.X before 1.43.2.","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":"CheckUser: Reflected Cross-Site Scripting (XSS) in Special:Investigate via unsanitized i18n messages","id":"CVE-2025-53478","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"CheckUser: Reflected Cross-Site Scripting (XSS) in Special:CheckUser via unsanitized internationalized message","id":"CVE-2025-53479"},"packages":[],"prev":{"headline":"Apache Mynewt NimBLE: NULL Pointer Dereference in NimBLE host HCI layer","id":"CVE-2025-53477"},"products":["Mediawiki - CheckUser extension"],"published":"2025-07-07","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":"2025-07-07","vendors":["Wikimedia Foundation"]},"summary":"Reflected XSS in MediaWiki CheckUser extension allows attackers to execute scripts via unsanitized i18n messages on the Investigate page.","url":"https://insights.sbomify.com/CVE-2025-53478/"}
