Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-58028 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-2026-58028/ (Markdown: https://insights.sbomify.com/CVE-2026-58028/index.md)","id":"CVE-2026-58028","markdown":"https://insights.sbomify.com/CVE-2026-58028/index.md","name":"CVE-2026-58028","record":{"aliases":["DEBIAN-CVE-2026-58028","GHSA-jqc3-4vrw-8965","MINI-cg49-8px4-hv37","MINI-pc67-px3c-xcmc","MINI-rc7q-5vv5-jmv6","UBUNTU-CVE-2026-58028"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki CentralAuth","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary scripts via XSS in MediaWiki API output when using CentralAuth, potentially compromising user accounts.","user_interaction":"not_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:N/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, Wikimedia Foundation CentralAuth.\n\n This vulnerability is associated with program files includes/Api/ApiFormatBase.Php, includes/Api/ApiHelp.Php, includes/ResourceLoader/Module.Php, includes/Hooks/Handlers/PageDisplayHookHandler.Php, includes/LogFormatter/PermissionChangeLogFormatter.Php.\n\nThis issue affects MediaWiki: from * before 1.46.0, 1.45.4, 1.44.6, 1.43.9; CentralAuth: 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":"Pretty-printed API output combined with centralauthtoken allows XSS with certain gadgets","id":"CVE-2026-58028","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":"Full Account Takeover from BotPasswords and OAuth via action=changeauthenticationdata","id":"CVE-2026-58029"},"packages":[],"prev":{"headline":"QueryAbuseFilter API can be used to see the hit count of private filters, which is hidden in the UI","id":"CVE-2026-58027"},"products":["CentralAuth","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":"Attackers can execute arbitrary scripts via XSS in MediaWiki API output when using CentralAuth, potentially compromising user accounts.","url":"https://insights.sbomify.com/CVE-2026-58028/"}
