Stored Cross-Site Scripting in Podcast Subscribe Buttons Plugin for WordPress

CVE-2023-5308

Summary

The Podcast Subscribe Buttons plugin for WordPress features a vulnerability that allows for Stored Cross-Site Scripting attacks. This flaw arises from lack of proper input sanitization and output escaping for user-supplied attributes through the 'podcast_subscribe' shortcode in versions up to and including 1.4.8. Authenticated users with contributor-level and higher permissions can exploit this vulnerability by injecting malicious scripts into pages. These scripts will execute when other users access the compromised content, potentially compromising the security of those users and the integrity of the website.
