An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-62698 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation Mediawiki - ExternalGuidance. 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-2025-62698/ (Markdown: https://insights.sbomify.com/CVE-2025-62698/index.md)","id":"CVE-2025-62698","markdown":"https://insights.sbomify.com/CVE-2025-62698/index.md","name":"CVE-2025-62698","record":{"aliases":["GHSA-qwr4-3w57-c2xx","UBUNTU-CVE-2025-62698"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki ExternalGuidance","requires_auth":"none","summary":"Stored XSS in MediaWiki ExternalGuidance allows attackers to inject scripts via system messages, potentially compromising user sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in The Wikimedia Foundation Mediawiki - ExternalGuidance allows Stored XSS.This issue affects Mediawiki - ExternalGuidance: from master before 1.39.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Stored XSS through system messages in ExternalGuidance","id":"CVE-2025-62698","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Special:Translate tool does not use the correct IP and User-Agent in the CheckUser tool","id":"CVE-2025-62699"},"packages":[],"prev":{"headline":"Improperly sanitized style parameter in LanguageSelector","id":"CVE-2025-62697"},"products":["Mediawiki - ExternalGuidance"],"published":"2025-10-20","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-20","vendors":["The Wikimedia Foundation"]},"summary":"Stored XSS in MediaWiki ExternalGuidance allows attackers to inject scripts via system messages, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2025-62698/"}
