An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-96872 and fix it if it is affected.\n\nWhat it is: CVE-2026-96872 is a low-severity missing authorization vulnerability in The Wikimedia Foundation Mediawiki - WikiLambda Extension, published on 23 Sep 2026. 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-2026-96872 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-2026-96872/ (Markdown: https://insights.sbomify.com/CVE-2026-96872/index.md)","id":"CVE-2026-96872","markdown":"https://insights.sbomify.com/CVE-2026-96872/index.md","name":"CVE-2026-96872","record":{"aliases":["GHSA-c7v9-97f3-3pxf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki WikiLambda extension","requires_auth":"none","summary":"Attackers can execute unsaved code via nested compositions, bypassing permission checks in the WikiLambda extension.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":2.9,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:P/AU:Y","version":"4.0"},"cwes":[{"id":"CWE-280","name":"Improper Handling of Insufficient Permissions or Privileges"}],"description":"Improper handling of insufficient permissions or privileges vulnerability in The Wikimedia Foundation Mediawiki - WikiLambda Extension on Linux, MacOS, and Windows allows Accessing Functionality Not Properly Constrained by ACLs.\n\nThis issue affects Mediawiki - WikiLambda Extension: before 1.47.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-29","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-29T14:27:42Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-96872","stars":0,"title":"Sanitized WikiLambda report and patch verification notes for CVE-2026-96872."}],"tier":"poc_unverified"},"has_fix":null,"headline":"WikiLambda public function execution bypasses the unsaved-code permission through nested Z825 compositions","id":"CVE-2026-96872","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":"Reflected XSS in CirrusSearch debug explain output","id":"CVE-2026-96873"},"packages":[],"prev":{"headline":"Mang Board \u003c= 2.4.2 - Unauthenticated Stored Cross-Site Scripting via 'data_type' Parameter","id":"CVE-2026-96871"},"products":["Mediawiki - WikiLambda Extension"],"published":"2026-09-23","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":"2026-09-23","vendors":["The Wikimedia Foundation"]},"summary":"Attackers can execute unsaved code via nested compositions, bypassing permission checks in the WikiLambda extension.","url":"https://insights.sbomify.com/CVE-2026-96872/"}
