Impact Analysis

This vulnerability can have severe impacts including unauthorized access to your website.

Attackers can upload backdoors or web shells, which allow them to execute arbitrary commands, manipulate website content, steal data, or use the site as a platform for further attacks.

Such unauthorized control can lead to website defacement, data breaches, loss of customer trust, and potential downtime.

Because the vulnerability requires only subscriber-level access, it increases the risk that even low-privileged users can compromise the site.
