{"id":"CVE-2026-6401","state":"PUBLISHED","title":"Bottom Bar <= 0.1.7 - Cross-Site Request Forgery to Settings Update","description":"The Bottom Bar plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 0.1.7. This is due to missing nonce verification on the plugin's settings update forms handled in bottom-bar-admin.php. None of the three settings forms (main settings, sharing services, restore defaults) include a wp_nonce_field(), and the server-side processing code never calls check_admin_referer() or any equivalent nonce validation before processing POST data and calling update_option(). This makes it possible for unauthenticated attackers to trick a logged-in administrator into submitting a crafted request that updates plugin configuration options, such as changing the language, maximum post counts, or enabled sharing services.","publishedAt":"2026-05-20T01:25:55.419Z","updatedAt":"2026-05-20T14:15:50.660Z","severity":{"score":4.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["svil4ok Bottom Bar"],"affected":[{"vendor":"svil4ok","product":"Bottom Bar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"0.1.7","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/db0715ed-a06e-4a68-b9c3-408887cae113?source=cve","https://plugins.trac.wordpress.org/browser/bottom-bar/trunk/bottom-bar-admin.php#L16","https://plugins.trac.wordpress.org/browser/bottom-bar/tags/0.1.7/bottom-bar-admin.php#L16","https://plugins.trac.wordpress.org/browser/bottom-bar/trunk/bottom-bar-admin.php#L59","https://plugins.trac.wordpress.org/browser/bottom-bar/tags/0.1.7/bottom-bar-admin.php#L59"],"weaknesses":["CWE-352"],"ingestedAt":"2026-10-29T20:12:49.727Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/6xxx/CVE-2026-6401.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-6401","state":"PUBLISHED","datePublished":"2026-05-20T01:25:55.419Z","dateUpdated":"2026-05-20T14:15:50.660Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-04-15T20:30:08.265Z"},"containers":{"cna":{"title":"Bottom Bar <= 0.1.7 - Cross-Site Request Forgery to Settings Update","descriptions":[{"lang":"en","value":"The Bottom Bar plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to and including 0.1.7.
