CVE-2025-14353 in ZIP Code Based Content Protection Plugin
Summary
by MITRE • 03/07/2026
The ZIP Code Based Content Protection plugin for WordPress is vulnerable to SQL Injection in all versions up to, and including, 1.0.2 via the 'zipcode' parameter. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The vulnerability identified as CVE-2025-14353 affects the ZIP Code Based Content Protection plugin for WordPress, representing a critical security flaw that has persisted across all versions up to and including 1.0.2. This plugin is designed to restrict content access based on geographic zip codes, but the implementation contains a fundamental flaw in its database query handling mechanism. The vulnerability manifests through the 'zipcode' parameter which is directly incorporated into SQL queries without proper sanitization or parameterization, creating an exploitable entry point for malicious actors.
The technical root cause of this vulnerability can be classified as CWE-89 SQL Injection, where the plugin fails to properly escape user-supplied input before incorporating it into database queries. The insufficient escaping mechanism allows attackers to manipulate the SQL query structure by injecting malicious SQL fragments through the zipcode parameter. This lack of proper input validation and query preparation creates a condition where an attacker can append additional SQL commands to the existing query, effectively bypassing the intended access controls. The vulnerability is particularly concerning because it affects an unauthenticated attack vector, meaning any visitor to the WordPress site can potentially exploit this flaw without requiring prior authorization or credentials.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to extract sensitive information from the underlying database. An attacker could potentially retrieve user credentials, personal information, configuration details, or other confidential data stored within the WordPress database. The vulnerability undermines the core security model of the plugin, which is intended to provide geographic access control, by allowing unauthorized users to bypass these restrictions entirely. Given that this affects a WordPress plugin, the potential attack surface includes not just the specific zip code functionality but also the broader WordPress installation, as database access could enable further exploitation through chained attacks.
Mitigation strategies for this vulnerability should prioritize immediate plugin updates to versions that address the SQL injection flaw through proper parameterization and input sanitization. System administrators should implement additional security measures including web application firewalls that can detect and block SQL injection attempts, database query logging to monitor for suspicious activity, and regular security audits of installed plugins. The ATT&CK framework categorizes this vulnerability under T1190 Exploit Public-Facing Application, with potential lateral movement opportunities through credential theft or data exfiltration. Organizations should also consider implementing database access controls that limit the privileges of the WordPress application user, reducing the potential impact of successful exploitation. Regular patch management processes should be enhanced to ensure all WordPress plugins and themes are kept current with security updates, as this vulnerability demonstrates the importance of maintaining up-to-date security controls in web applications.
