CVE-2025-64427: Zimaspace Zimaos

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

ZimaOS is a fork of CasaOS, an operating system for Zima devices and x86-64 systems with UEFI. In version 1.5.0 and prior, due to insufficient validation or restriction of target URLs, an authenticated local user can craft requests that target internal IP addresses (e.g., 127.0.0.1, localhost, or private network ranges). This allows the attacker to interact with internal HTTP/HTTPS services that are not intended to be exposed externally or to local users. No known patch is publicly available.

Affected products

• Zimaspace Zimaos: up to and including 1.5.0
