CVE-2026-4084 describes a Stored Cross-Site Scripting (XSS) vulnerability in the fyyd podcast shortcodes plugin for WordPress, affecting all versions up to 0.3.1. This flaw arises from insufficient input sanitization and output escaping of user-supplied shortcode attributes, enabling authenticated attackers with Contributor-level access or higher to inject malicious web scripts. With a CVSS score of 6.4 (Medium) and low attack complexity, successful exploitation allows arbitrary script execution in a victim's browser when they access an affected page. Currently, there is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
