The Podcast Subscribe Buttons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'podcast_subscribe' shortcode in versions up to, and including, 1.4.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
The Podcast Importer SecondLine WordPress plugin before 1.3.8 does not sanitise and properly escape some imported data, which could allow SQL injection attacks to be performed by imported a malicious podcast file
