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-2026-103446 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation MediaWiki WikiLambda 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-2026-103446/ (Markdown: https://insights.sbomify.com/CVE-2026-103446/index.md)","id":"CVE-2026-103446","markdown":"https://insights.sbomify.com/CVE-2026-103446/index.md","name":"CVE-2026-103446","record":{"aliases":["GHSA-4x94-p99h-wrcj"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki WikiLambda extension","requires_auth":"low_privilege","summary":"Attackers can bypass authentication to access unsaved Abstract Wikipedia fragments in the WikiLambda extension, exposing sensitive draft data.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P/S:N/AU:Y/R:U/V:C/RE:M/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Authorization bypass through User-Controlled key vulnerability in The Wikimedia Foundation MediaWiki WikiLambda extension allows Authentication Bypass.\n\nThis issue affects MediaWiki WikiLambda extension: 1.46.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-30","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-30T18:34:26Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-103446","stars":0,"title":"Sanitized report summary and local PoC for CVE-2026-103446"}],"tier":"poc_unverified"},"has_fix":null,"headline":"WikiLambda exposes anonymous execution of unsaved Abstract Wikipedia fragments","id":"CVE-2026-103446","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Privilege escalation in Grouper","id":"CVE-2026-103470"},"packages":[],"prev":{"headline":"Stored XSS through PageForms #autoedit redirect links","id":"CVE-2026-103445"},"products":["MediaWiki WikiLambda 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":"total"},"state":"PUBLISHED","updated":"2026-10-06","vendors":["The Wikimedia Foundation"]},"summary":"Attackers can bypass authentication to access unsaved Abstract Wikipedia fragments in the WikiLambda extension, exposing sensitive draft data.","url":"https://insights.sbomify.com/CVE-2026-103446/"}
