Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-103440 and fix it if it is affected.\n\nWhat it is: CVE-2026-103440 is a low-severity vulnerability in The Wikimedia Foundation MediaWiki PageTriage extension, published on 30 Sep 2026. 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-2026-103440 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation MediaWiki PageTriage 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-2026-103440/ (Markdown: https://insights.sbomify.com/CVE-2026-103440/index.md)","id":"CVE-2026-103440","markdown":"https://insights.sbomify.com/CVE-2026-103440/index.md","name":"CVE-2026-103440","record":{"aliases":["GHSA-vp5g-xhpv-4wq4"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki PageTriage extension","requires_auth":"low_privilege","summary":"The PageTriage extension leaks suppressed reviewer usernames, allowing attackers to identify users who have been hidden from public view.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":1.2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L/E:P/S:N/AU:Y/R:U/V:D/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-202","name":"Exposure of Sensitive Information Through Data Queries"}],"description":"Exposure of sensitive information through data queries vulnerability in The Wikimedia Foundation MediaWiki PageTriage extension allows Information Elicitation.\n\nThis issue affects MediaWiki PageTriage extension: 1.46, 1.45, and 1.43.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-30","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-30T18:34:02Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-103440","stars":0,"title":"Sanitized report summary and local PoC for CVE-2026-103440"}],"tier":"poc_unverified"},"has_fix":null,"headline":"pagetriagelist discloses suppressed reviewer usernames","id":"CVE-2026-103440","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":"Unauthenticated arbitrary file deletion through Wikibase serialized entity parsing","id":"CVE-2026-103441"},"packages":[],"prev":{"headline":"Various rawParams() and escaped() updates to prevent XSS in Wikibase extension","id":"CVE-2026-103439"},"products":["MediaWiki PageTriage extension"],"published":"2026-09-30","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["The Wikimedia Foundation"]},"summary":"The PageTriage extension leaks suppressed reviewer usernames, allowing attackers to identify users who have been hidden from public view.","url":"https://insights.sbomify.com/CVE-2026-103440/"}
