Input validation vulnerability in Table Maker 1.9.1

The Table Maker plugin for WordPress is not secure and can be easily hacked by malicious users. This can happen in any version up to 1.9.1 of the plugin. The problem is that the plugin does not properly protect against harmful scripts, which can be injected into pages by attackers with Author-level access or higher. This means that whenever a user visits a page with the injected script, it will run and potentially cause harm.
