Input validation vulnerability in eTemplates 0.2.1

The eTemplates plugin for WordPress, up to and including version 0.2.1, is at risk of a type of cyber attack called SQL Injection. This is because it does not have enough protection in place for user input and does not properly prepare its existing database queries. This vulnerability can allow unauthorized individuals to add their own malicious code to existing queries, which could result in them accessing private information from the database.
