Impact Analysis

This vulnerability can allow attackers with low-level access (e.g., Subscriber role) to perform unauthorized actions that should be restricted to higher privilege users.

Such unauthorized actions could lead to compromise of the integrity of the system, potentially allowing attackers to manipulate or misuse the plugin's functionality.
