Impact Analysis

This vulnerability can allow attackers to upload and execute malicious files such as web shells on your web server.

Attackers can use these backdoors to gain unauthorized access, potentially leading to data theft, website defacement, or complete server compromise.

Since the vulnerability requires only subscriber-level access, it is particularly dangerous for WordPress sites using the Nutrie Theme before version 2.0.1.

Immediate updating to version 2.0.1 or later is necessary to mitigate this risk.
