An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-62665 exists.\n\nAffected product: Wikimedia Foundation Mediawiki - Skin:BlueSky. 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-2025-62665/ (Markdown: https://insights.sbomify.com/CVE-2025-62665/index.md)","id":"CVE-2025-62665","markdown":"https://insights.sbomify.com/CVE-2025-62665/index.md","name":"CVE-2025-62665","record":{"aliases":["GHSA-h73w-rr6h-gjf4"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki skin","requires_auth":"none","summary":"Attackers can inject malicious scripts via system messages in the BlueSky skin, 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:N/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 Wikimedia Foundation Mediawiki - Skin:BlueSky allows Stored XSS.This issue affects Mediawiki - Skin:BlueSky: 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":"weaponised"},"has_fix":null,"headline":"Stored XSS through system messages in Skin:BlueSky","id":"CVE-2025-62665","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"DoS vector through the cirrusbuilddoc query API","id":"CVE-2025-62666"},"packages":[],"prev":{"headline":"Stored XSS through a system message in ImageRating","id":"CVE-2025-62664"},"products":["Mediawiki - Skin:BlueSky"],"published":"2025-10-18","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-20","vendors":["Wikimedia Foundation"]},"summary":"Attackers can inject malicious scripts via system messages in the BlueSky skin, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2025-62665/"}
