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-2025-62669 exists.\n\nAffected product: The Wikimedia Foundation Mediawiki - CentralAuth 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-2025-62669/ (Markdown: https://insights.sbomify.com/CVE-2025-62669/index.md)","id":"CVE-2025-62669","markdown":"https://insights.sbomify.com/CVE-2025-62669/index.md","name":"CVE-2025-62669","record":{"aliases":["GHSA-54m9-295v-m438"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki CentralAuth Extension","requires_auth":"none","summary":"An attacker can access sensitive information via the CentralAuth extension due to missing permission checks in the UserInfoCard component.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of Sensitive Information to an Unauthorized Actor vulnerability in The Wikimedia Foundation Mediawiki - CentralAuth Extension allows Resource Leak Exposure.This issue affects Mediawiki - CentralAuth Extension: 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":"UserInfoCard: activeLocalBlocksAllWikis does not do permissions checks","id":"CVE-2025-62669","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2025"},"n_packages":0,"n_references":2,"next":{"headline":"Stored XSS through a system message in FlexDiagrams","id":"CVE-2025-62670"},"packages":[],"prev":{"headline":"Insufficient permission checks in action=growthsetmentor","id":"CVE-2025-62668"},"products":["Mediawiki - CentralAuth Extension"],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-20","vendors":["The Wikimedia Foundation"]},"summary":"An attacker can access sensitive information via the CentralAuth extension due to missing permission checks in the UserInfoCard component.","url":"https://insights.sbomify.com/CVE-2025-62669/"}
