What is CVE-2025-13893?

The Lesson Plan Book plugin for WordPress is susceptible to Reflected Cross-Site Scripting due to inadequate input sanitization and output escaping in all versions up to and including 1.3. By exploiting the $_SERVER['PHP_SELF'] variable, attackers can inject malicious scripts that may execute in the context of a user’s session, given that the user interacts with a crafted link. This vulnerability highlights the importance of thorough validation and escaping to protect against script injection attacks.
