Technical details
The plugin fails to properly sanitize the base-url attribute in [mpg] and [mpg_match] shortcodes. Attackers inject entity-encoded payloads that bypass WordPress kses sanitization, then are decoded by html_entity_decode() and rendered unescaped through the {{mpg_url}} template variable, resulting in stored XSS. The vulnerability requires contributor-level access (ability to publish posts/pages with shortcodes).
