The Chameleon CSS WordPress plugin through 1.2 does not have any CSRF and capability checks in all its AJAX calls, allowing any authenticated user, such as subscriber to call them and perform unauthorised actions. One of AJAX call, remove_css, also does not sanitise or escape the css_id POST parameter before using it in a SQL statement, leading to a SQL Injection
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
