## Technical details

A static code injection vulnerability exists in Plesk's Ruby extension (before 1.6.6) and Node.js Toolkit extension (before 2.5.0). The vulnerability allows remote authenticated users to execute arbitrary code with root privileges by manipulating custom environment variables. The flaw does not require special privileges beyond authentication to the Plesk control panel, and exploitation results in arbitrary code execution at the system's highest privilege level.

## Affected products

- Plesk Ruby extension before 1.6.6
- Plesk Node.js Toolkit extension before 2.5.0
