Input validation vulnerability in Leadster 1.1.2

The Leadster plugin for WordPress is vulnerable to a type of attack known as Cross-Site Request Forgery. This vulnerability affects versions of Leadster up to and including 1.1.2. It exists because the leadster_script_code_action function does not include the necessary security measures to prevent it. An unauthenticated attacker could exploit this vulnerability by tricking a site administrator into clicking on a malicious link, which would then modify the Leadster script code.
