Stored XSS via unescaped shortcode attributes
Published Feb 6, 2023 · Updated Mar 25, 2025
Stored XSS in RexTheme WP VR before 8.2.7 allows remote authenticated users to inject scripts through crafted shortcode attributes. The wpvr shortcode handler writes the width attribute into page markup without validating or escaping attacker-controlled content. Contributor-level access is required, and the script runs when another user views the affected page or post in that user’s browser context.
