An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-58519 exists.\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-2026-58519/ (Markdown: https://insights.sbomify.com/CVE-2026-58519/index.md)","id":"CVE-2026-58519","markdown":"https://insights.sbomify.com/CVE-2026-58519/index.md","name":"CVE-2026-58519","record":{"aliases":["GHSA-r23x-87q7-xq2f"],"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":"Stored XSS in MediaWiki Cargo Extension allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"cargo","vendor":"mediawiki"}],"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:L/VA:L/SC:L/SI:L/SA:L/E:A","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 The Wikimedia Foundation Mediawiki - Cargo Extension allows Stored XSS.\n\nThis issue affects Mediawiki - Cargo Extension: from * before 3.9.1.","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":"Stored XSS through Cargo's map format","id":"CVE-2026-58519","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"UrlShortener defaults to ineffective validation open to third-party redirects","id":"CVE-2026-58520"},"packages":[],"prev":{"headline":"Cross-site request forgery in Mediawiki - RedirectManager Extension","id":"CVE-2026-58518"},"products":["Mediawiki - Cargo Extension"],"published":"2026-07-01","related":[{"cvss_score":8.8,"headline":"Backticks can allow the usage of not-allowed SQL functions","id":"CVE-2024-47849","kev_date_added":null,"published":"2024-10-05"},{"cvss_score":6.9,"headline":"Cargo Extension: SQLi in Special:Drilldown","id":"CVE-2026-14363","kev_date_added":null,"published":"2026-07-01"},{"cvss_score":6.9,"headline":"SQLi in Cargo extension via year range filter","id":"CVE-2026-58521","kev_date_added":null,"published":"2026-07-01"},{"cvss_score":6.9,"headline":"Special:DeleteCargoTable and Special:SwitchCargoTable have no CSRF protection","id":"CVE-2024-47846","kev_date_added":null,"published":"2024-10-05"},{"cvss_score":6.9,"headline":"Various XSSes found in Cargo","id":"CVE-2024-47847","kev_date_added":null,"published":"2024-10-05"},{"cvss_score":6.3,"headline":"Stored XSS through the dynamic table format in Cargo","id":"CVE-2026-39837","kev_date_added":null,"published":"2026-04-07"}],"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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-01","vendors":["The Wikimedia Foundation"]},"summary":"Stored XSS in MediaWiki Cargo Extension allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2026-58519/"}
