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."}],"title":"Bottom Bar <= 0.1.7 - Cross-Site Request Forgery to Settings Update","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/db0715ed-a06e-4a68-b9c3-408887cae113?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/bottom-bar/trunk/bottom-bar-admin.php#L16"},{"url":"https://plugins.trac.wordpress.org/browser/bottom-bar/tags/0.1.7/bottom-bar-admin.php#L16"},{"url":"https://plugins.trac.wordpress.org/browser/bottom-bar/trunk/bottom-bar-admin.php#L59"},{"url":"https://plugins.trac.wordpress.org/browser/bottom-bar/tags/0.1.7/bottom-bar-admin.php#L59"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-352 Cross-Site Request Forgery (CSRF)","cweId":"CWE-352","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","baseScore":4.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Muhammad Nur Ibnu Hubab"}],"timeline":[{"time":"2026-05-19T12:04:46.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-20T14:15:40.602011Z","id":"CVE-2026-6401","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-20T14:15:50.660Z"}}]}}
