Input validation vulnerability in Custom 404 Pro 3.7.3

  • Severity: critical
  • Status: Open
  • Publication: April 25, 2023

The Custom 404 Pro plugin for WordPress is vulnerable to a type of cyber attack called a blind SQL Injection. This type of attack can be used to access sensitive information from a database. The plugin has versions up to and including 3.7.2 that are vulnerable to this attack because of the way the user supplied parameters have not been properly escaped and the existing SQL query was not properly prepared. This makes it possible for an unauthenticated attacker to add additional SQL queries to the existing query.
