Input validation vulnerability in Simple Link Directory Pro 14.7.3

The Simple Link Directory plugin for WordPress has a security issue that could allow hackers to access sensitive information from the database. This is because the plugin does not properly protect against SQL Injection, which means that attackers could add their own code to the existing queries and gain access to private data. This vulnerability exists in versions up to and including 14.7.3 and can be exploited by users with subscriber-level access or higher.
