CWE-1188Published: January 8, 2026· Updated: Jun 17, 2026

9.8

CVSS v3.1

Official Description

Projects using the SUSE Virtualization (Harvester) environment may expose the OS default ssh login password if they are using the 1.5.x or 1.6.x interactive installer to either create a new cluster or add new hosts to an existing cluster. The environment is not affected if the PXE boot mechanism is utilized along with the Harvester configuration setup.

Risk Analysis

This critical vulnerability in SUSE Virtualization (Harvester) 1.5.x and 1.6.x interactive installers exposes the OS default SSH login password. With a CVSS score of 9.8, this flaw presents a severe risk of complete system compromise, making it an urgent concern.

No public exploit is currently known for this vulnerability. Its remote exploitability (AV:N) and low attack complexity (AC:L) mean it could be easily exploited by an unauthenticated attacker.

Recommended Action

Avoid using the interactive installer for Harvester 1.5.x and 1.6.x; instead, utilize the PXE boot mechanism with Harvester configuration setup. Immediately change default SSH passwords on any affected systems.
