Original description
The Image Alt Text Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the post title in all versions up to, and including, 1.8.2. This is due to insufficient input sanitization and output escaping when dynamically generating image alt and title attributes using a DOM parser. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
