Description
The Testimonial Customer Feedback plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' attribute of the plugin's [TML] shortcode in all versions up to, and including, 1.2.8 due to insufficient input sanitization and output escaping that does not fit the context. The 'id' value is placed into inline JavaScript, including as part of function names, with only esc_attr(), which does not prevent JavaScript injection in that context. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
