Twitter Feed WordPress Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Twitter Feed plugin for WordPress, affecting all versions through 1.3.1. The issue arises from the plugin's failure to properly sanitize user input and output for the 'width' and 'height' parameters in the 'ottwitter_feed' shortcode. This vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.
