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-2026-96873 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation Mediawiki - CirrusSearch 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-2026-96873/ (Markdown: https://insights.sbomify.com/CVE-2026-96873/index.md)","id":"CVE-2026-96873","markdown":"https://insights.sbomify.com/CVE-2026-96873/index.md","name":"CVE-2026-96873","record":{"aliases":["GHSA-fv8h-v7wg-hwcx"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki CirrusSearch extension","requires_auth":"none","summary":"Reflected XSS in MediaWiki CirrusSearch debug output allows attackers to execute arbitrary scripts in user browsers.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","version":"4.0"},"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 Mediawiki - CirrusSearch extension allows Reflected XSS.\n\nThis issue affects Mediawiki - CirrusSearch extension through 1.46.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-29","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-29T14:27:49Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-96873","stars":0,"title":"Sanitized CirrusSearch report and patch verification notes for CVE-2026-96873."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Reflected XSS in CirrusSearch debug explain output","id":"CVE-2026-96873","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 in Cargo Drilldown tab names","id":"CVE-2026-96874"},"packages":[],"prev":{"headline":"WikiLambda public function execution bypasses the unsaved-code permission through nested Z825 compositions","id":"CVE-2026-96872"},"products":["Mediawiki - CirrusSearch Extension"],"published":"2026-09-24","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":"2026-09-29","vendors":["The Wikimedia Foundation"]},"summary":"Reflected XSS in MediaWiki CirrusSearch debug output allows attackers to execute arbitrary scripts in user browsers.","url":"https://insights.sbomify.com/CVE-2026-96873/"}
