A stored cross-site scripting vulnerability has been identified in the MetForm WordPress plugin, specifically in versions through 4.0.1. This issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts into pages. The injected scripts are executed when users access the compromised pages.
