Input validation vulnerability in Zoho Campaigns 2.0.6

The Zoho Campaigns plugin for WordPress has a security issue that allows hackers to access sensitive information from the database. This happens because the plugin does not properly protect against SQL Injection, which is a type of attack that can manipulate the code and extract data. This vulnerability exists in all versions up to 2.0.6 and can be exploited by authenticated attackers who have contributor-level access or higher.
