CVE-2025-9947: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in kunalnagar Custom 404 Pro
The Custom 404 Pro plugin for WordPress is vulnerable to time-based SQL Injection via the ‘path’ parameter in all versions up to, and including, 3.12.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
AI Analysis
Technical Summary
CVE-2025-9947 describes a time-based SQL Injection vulnerability in the Custom 404 Pro WordPress plugin (up to version 3.12.0). The issue arises from insufficient escaping of the user-supplied ‘path’ parameter and lack of proper SQL query preparation, enabling authenticated administrators to append malicious SQL commands. This vulnerability allows unauthorized extraction of sensitive data from the backend database. The attack requires high privileges (Administrator or above) and does not affect system availability or integrity beyond data confidentiality.
Potential Impact
An attacker with Administrator-level access can exploit this vulnerability to perform time-based SQL Injection attacks, potentially extracting sensitive information from the database. The vulnerability does not impact data integrity or availability but compromises confidentiality. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator-level access to trusted users only and monitor for suspicious activity related to the ‘path’ parameter. Avoid using vulnerable versions of the plugin if possible.
