Impact Analysis

This vulnerability allows unauthenticated users to perform actions reserved for privileged users, potentially leading to unauthorized privilege escalation.

Such unauthorized access can compromise the security and integrity of your WordPress site by allowing attackers to manipulate subscription-related functions without proper permissions.

Because no prior authentication is required, the risk of exploitation is higher, increasing the likelihood of unauthorized actions being performed.
