Overview
Affected versions of this package are vulnerable to SQL Injection via the deletePage process. An attacker can execute arbitrary SQL commands and exfiltrate sensitive data or disrupt database integrity by crafting a malicious page tag, making it non-orphaned through legitimate linking mechanisms, and then invoking the delete endpoint. This allows the attacker to perform time-based blind data extraction or delete large portions of the database.
