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-2026-96879 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation Mediawiki - FlaggedRevs 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-2026-96879/ (Markdown: https://insights.sbomify.com/CVE-2026-96879/index.md)","id":"CVE-2026-96879","markdown":"https://insights.sbomify.com/CVE-2026-96879/index.md","name":"CVE-2026-96879","record":{"aliases":["GHSA-xxh4-xg3q-g2r6"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki FlaggedRevs extension","requires_auth":"none","summary":"Attackers can view suppressed review log entries via the page history 'Checked by' label, exposing sensitive moderation data.","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:N/VA:N/SC:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-212","name":"Improper Removal of Sensitive Information Before Storage or Transfer"}],"description":"Improper removal of sensitive information before storage or transfer vulnerability in Wikimedia Foundation's Mediawiki - FlaggedRevs extension through 1.46.0.","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":"\"Checked by\" label in page history should not be shown if the underlying review log entry is suppressed\"","id":"CVE-2026-96879","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"TaleLin lin-cms-spring-boot book Endpoint BookController.java getBook improper authorization","id":"CVE-2026-96880"},"packages":[],"prev":{"headline":"Cargo Exhibit field alias allows stored XSS","id":"CVE-2026-96878"},"products":["Mediawiki - FlaggedRevs extension"],"published":"2026-09-25","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":"2026-09-29","vendors":["The Wikimedia Foundation"]},"summary":"Attackers can view suppressed review log entries via the page history 'Checked by' label, exposing sensitive moderation data.","url":"https://insights.sbomify.com/CVE-2026-96879/"}
