An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-29004 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- mediawiki (Bitnami): affected all versions; fixed in 1.35.1\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-2020-29004/ (Markdown: https://insights.sbomify.com/CVE-2020-29004/index.md)","id":"CVE-2020-29004","markdown":"https://insights.sbomify.com/CVE-2020-29004/index.md","name":"CVE-2020-29004","record":{"aliases":["BIT-mediawiki-2020-29004","GHSA-m989-hhx2-g8c7"],"analysis":{"component_type":"cms_plugin","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MediaWiki Push extension","requires_auth":"none","summary":"Attackers can perform unauthorized actions via CSRF because the MediaWiki Push extension API lacks edit token validation.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"mediawiki","vendor":"mediawiki"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"The API in the Push extension for MediaWiki through 1.35 did not require an edit token in ApiPushBase.php and therefore facilitated a CSRF attack.","ecosystems":["Bitnami"],"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":"Cross-site request forgery in n/a","id":"CVE-2020-29004","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"mediawiki:mediawiki","products":["mediawiki:mediawiki"],"type":"csrf","year":"2020"},"n_packages":1,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-29005"},"packages":[{"ecosystem":"Bitnami","fixed":["1.35.1"],"introduced":["0"],"last_affected":[],"package":"mediawiki","purl":"pkg:bitnami/mediawiki","source":"BIT-mediawiki-2020-29004"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-29003"},"products":["n/a"],"published":"2021-01-29","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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can perform unauthorized actions via CSRF because the MediaWiki Push extension API lacks edit token validation.","url":"https://insights.sbomify.com/CVE-2020-29004/"}
