Input validation vulnerability in Churel 1.0.8

The Churel theme for WordPress has a security issue called Stored Cross-Site Scripting, which affects versions 1.0.8 and below. This is because the theme does not properly clean up or protect against harmful code. Attackers who are logged in with contributor-level access or higher can take advantage of this vulnerability to insert their own malicious code into pages. This code will then run whenever a user visits that page.
