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-2026-96876 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-2026-96876/ (Markdown: https://insights.sbomify.com/CVE-2026-96876/index.md)","id":"CVE-2026-96876","markdown":"https://insights.sbomify.com/CVE-2026-96876/index.md","name":"CVE-2026-96876","record":{"aliases":["GHSA-vhv7-3w94-fpq6"],"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":"An attacker can execute arbitrary scripts in a victim's browser via reflected XSS in the Cargo extension's error handling.","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":"2026-09-29T14:28:11Z","kind":"github_poc","ref":"https://github.com/BomboBombone/CVE-2026-96876","stars":0,"title":"Sanitized Cargo report and patch verification notes for CVE-2026-96876."}],"tier":"poc_unverified"},"has_fix":null,"headline":"Anonymous reflected XSS in CargoExport invalid-alias errors","id":"CVE-2026-96876","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Reflected XSS through Cargo Drilldown full-text search","id":"CVE-2026-96877"},"packages":[],"prev":{"headline":"Reflected XSS in Cargo Drilldown hierarchy filters","id":"CVE-2026-96875"},"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-29","vendors":["The Wikimedia Foundation"]},"summary":"An attacker can execute arbitrary scripts in a victim's browser via reflected XSS in the Cargo extension's error handling.","url":"https://insights.sbomify.com/CVE-2026-96876/"}
