Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-58037 in the wild and no public exploit code.\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-2026-58037/ (Markdown: https://insights.sbomify.com/CVE-2026-58037/index.md)","id":"CVE-2026-58037","markdown":"https://insights.sbomify.com/CVE-2026-58037/index.md","name":"CVE-2026-58037","record":{"aliases":["DEBIAN-CVE-2026-58037","GHSA-c9c4-xmc2-5h6x","MINI-9q2c-cq73-2xc4","MINI-fmgr-g2hr-gw7w","MINI-pvhq-q572-3735","UBUNTU-CVE-2026-58037"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki","requires_auth":"low_privilege","summary":"An attacker can inject malicious scripts via user-controlled input in log entries, potentially leading to code execution or data theft in MediaWiki installations.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"wikimedia-foundation","cpe":[{"product":"mediawiki","vendor":"mediawiki"}],"cvss":{"score":0,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:N/VA:N/SC:N/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 (XSS or 'Cross-site Scripting') vulnerability in Wikimedia Foundation MediaWiki.\n\n This vulnerability is associated with program files includes/Language/Language.Php, includes/Logging/BlockLogFormatter.Php, includes/Logging/LogFormatter.Php, includes/Logging/PatrolLogFormatter.Php, includes/Logging/RenameuserLogFormatter.Php, includes/Logging/TagLogFormatter.Php, includes/Specials/SpecialVersion.Php.\n\nThis issue affects MediaWiki: from * before 1.46.0, 1.45.4, 1.44.6, 1.43.9.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Core log entries for exceptions and XSS issues in log entry formatting code that may be caused by user-controlled input","id":"CVE-2026-58037","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"mediawiki:mediawiki","products":["mediawiki:mediawiki"],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Stored XSS through javascript URLs in SVGs generated by EasyTimeline","id":"CVE-2026-58038"},"packages":[],"prev":{"headline":"Users API leaks whether privileged users have their user groups disabled for lack of 2FA","id":"CVE-2026-58036"},"products":["MediaWiki"],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-01","vendors":["Wikimedia Foundation"]},"summary":"An attacker can inject malicious scripts via user-controlled input in log entries, potentially leading to code execution or data theft in MediaWiki installations.","url":"https://insights.sbomify.com/CVE-2026-58037/"}
