An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-103046 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-2026-103046/ (Markdown: https://insights.sbomify.com/CVE-2026-103046/index.md)","id":"CVE-2026-103046","markdown":"https://insights.sbomify.com/CVE-2026-103046/index.md","name":"CVE-2026-103046","record":{"aliases":["GHSA-wgjv-5xcv-4jq5","MINI-9895-mpmw-mw8v"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki WikiLambda extension","requires_auth":"none","summary":"Stored XSS in MediaWiki WikiLambda extension allows attackers to inject malicious scripts via unsafe HTML string replacements.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Wikimedia Foundation MediaWiki - WikiLambda extension allows Stored XSS.\n\nThis issue affects MediaWiki - WikiLambda extension: before 1.46.1.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"WikifunctionsFragmentRenderer does unsafe string replacements on user-provided HTML","id":"CVE-2026-103046","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"XSS through i18n message in CentralAuth","id":"CVE-2026-103047"},"packages":[],"prev":{"headline":"XSS in Refreshed skin","id":"CVE-2026-103045"},"products":["Mediawiki - WikiLambda Extension"],"published":"2026-09-29","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-30","vendors":["The Wikimedia Foundation"]},"summary":"Stored XSS in MediaWiki WikiLambda extension allows attackers to inject malicious scripts via unsafe HTML string replacements.","url":"https://insights.sbomify.com/CVE-2026-103046/"}
