## Description

The LIQUID SPEECH BALLOON plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the avatar settings in all versions up to, and including, 1.2.7, due to insufficient validation of the submitted avatar numbers (array keys of the liquid_speech_balloon_img and liquid_speech_balloon_name settings), which are output without escaping into an inline style block on every page. The settings page is also available to any user with the edit_posts capability. 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.
