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-2026-58518 exists.\n\nAffected product: Mediawiki Mediawiki. 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-2026-58518/ (Markdown: https://insights.sbomify.com/CVE-2026-58518/index.md)","id":"CVE-2026-58518","markdown":"https://insights.sbomify.com/CVE-2026-58518/index.md","name":"CVE-2026-58518","record":{"aliases":["GHSA-vjf9-r75w-m9fv"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki RedirectManager Extension","requires_auth":"none","summary":"Attackers can perform unauthorized actions on behalf of authenticated users via CSRF in the MediaWiki RedirectManager Extension.","user_interaction":"not_required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"mediawiki","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","version":"4.0"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"Cross-Site request forgery (CSRF) vulnerability in The Wikimedia Foundation Mediawiki - RedirectManager Extension allows Cross Site Request Forgery.\n\nThis issue affects Mediawiki - RedirectManager Extension: from * before 1.3.3.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Cross-site request forgery in Mediawiki - RedirectManager Extension","id":"CVE-2026-58518","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mediawiki:mediawiki","products":["mediawiki:mediawiki"],"type":"csrf","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Stored XSS through Cargo's map format","id":"CVE-2026-58519"},"packages":[],"prev":{"headline":"Blocked users can create and edit WikiLambda objects","id":"CVE-2026-58517"},"products":["Mediawiki - RedirectManager Extension"],"published":"2026-07-01","related":[{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2023-37303","kev_date_added":null,"published":"2023-06-30"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2022-29904","kev_date_added":null,"published":"2022-04-29"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-29906","kev_date_added":null,"published":"2022-04-29"},{"cvss_score":9.8,"headline":"Business logic in n/a","id":"CVE-2022-28205","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-28206","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2022-28209","kev_date_added":null,"published":"2022-03-30"},{"cvss_score":9.8,"headline":"Business logic in n/a","id":"CVE-2021-36126","kev_date_added":null,"published":"2021-07-02"}],"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":"Attackers can perform unauthorized actions on behalf of authenticated users via CSRF in the MediaWiki RedirectManager Extension.","url":"https://insights.sbomify.com/CVE-2026-58518/"}
