Stored cross-site scripting in Podcast Generator 3.2.9 allows remote authenticated users to execute JavaScript through Freebox content. The theme_freebox.php handler stores submitted content without neutralizing script markup, and the home page renders it as executable HTML. Administration access and a victim's home-page visit are required; exploitation runs script in the victim's browser context.
