The El mejor Cluster plugin for WordPress has a security issue known as Stored Cross-Site Scripting. This affects versions up to and including 1.1.14 and is caused by not properly cleaning and protecting user input. This means that someone with contributor-level access or higher can add harmful code into a page, which will then run whenever a user visits that page.
