High (8.8) in monstra monstra cms. EPSS 0.8% chance of exploitation in the next 30 days.

Monstra CMS v3.0.4 contains an arbitrary file upload vulnerability in the Files Manager plugin.

Under typical server configurations, this can allow an attacker to upload files that are interpreted as executable code, resulting in remote code execution.
