An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-22712 exists.\n\nAffected product: The Wikimedia Foundation Mediawiki - ApprovedRevs 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-2026-22712/ (Markdown: https://insights.sbomify.com/CVE-2026-22712/index.md)","id":"CVE-2026-22712","markdown":"https://insights.sbomify.com/CVE-2026-22712/index.md","name":"CVE-2026-22712","record":{"aliases":["GHSA-mrvc-5w25-h6c4"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki ApprovedRevs Extension","requires_auth":"none","summary":"Attackers can bypass the inline CSS sanitizer in the ApprovedRevs extension to inject malicious scripts, potentially leading to code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"approved_revs","vendor":"wikiworks"}],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:L/VI:L/VA:L/SC:L/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"Improper Encoding or Escaping of Output due to magic word replacement in ParserAfterTidy vulnerability in The Wikimedia Foundation Mediawiki - ApprovedRevs Extension allows Input Data Manipulation.This issue affects Mediawiki - ApprovedRevs Extension: 1.45, 1.44, 1.43, 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":"ApprovedRevs allows bypassing the inline CSS sanitizer","id":"CVE-2026-22712","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Stored XSS through edit summaries in GrowthExperiments","id":"CVE-2026-22713"},"packages":[],"prev":{"headline":"Stored XSS through system messages in WikiLove","id":"CVE-2026-22711"},"products":["Mediawiki - ApprovedRevs Extension"],"published":"2026-01-09","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-09","vendors":["The Wikimedia Foundation"]},"summary":"Attackers can bypass the inline CSS sanitizer in the ApprovedRevs extension to inject malicious scripts, potentially leading to code execution.","url":"https://insights.sbomify.com/CVE-2026-22712/"}
