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-2026-96877 in the wild and no public exploit code.\n\nAffected product: The Wikimedia Foundation Mediawiki - Cargo 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-2026-96877/ (Markdown: https://insights.sbomify.com/CVE-2026-96877/index.md)","id":"CVE-2026-96877","markdown":"https://insights.sbomify.com/CVE-2026-96877/index.md","name":"CVE-2026-96877","record":{"aliases":["GHSA-pq69-hr22-vjxq"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki Cargo extension","requires_auth":"none","summary":"Reflected XSS in MediaWiki Cargo extension allows attackers to execute scripts via full-text search, potentially compromising user sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[],"cvss":{"score":6.9,"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:L/SI:N/SA:N","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 - Cargo extension allows Reflected XSS.\n\nThis issue affects Mediawiki - Cargo extension: through 3.9.4.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-09-29","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-09-29T14:28:18Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-96877","stars":0,"title":"Sanitized Cargo report and patch verification notes for CVE-2026-96877."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Reflected XSS through Cargo Drilldown full-text search","id":"CVE-2026-96877","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Cargo Exhibit field alias allows stored XSS","id":"CVE-2026-96878"},"packages":[],"prev":{"headline":"Anonymous reflected XSS in CargoExport invalid-alias errors","id":"CVE-2026-96876"},"products":["Mediawiki - Cargo extension"],"published":"2026-09-25","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-29","vendors":["The Wikimedia Foundation"]},"summary":"Reflected XSS in MediaWiki Cargo extension allows attackers to execute scripts via full-text search, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2026-96877/"}
