Name of the Vulnerable Software and Affected Versions Schema & Structured Data for WP & AMP versions prior to 1.50

Description The Schema & Structured Data for WP & AMP WordPress plugin does not properly handle HTML tag attribute modifications. This allows unauthenticated attackers to conduct Stored Cross-Site Scripting (XSS) attacks via post comments. The issue involves overly-greedy regular expression replacements that bypass HTML sanitization, enabling the injection of malicious scripts. Exploitation involves crafting a payload that starts within one attribute value and ends in another, transforming sanitized HTML into XSS-able payloads through event handlers or javascript: URLs.

Recommendations Update Schema & Structured Data for WP & AMP to version 1.50 or later.
