CVE-2026-92761 in WebVirtCloud

Riassunto

di MITRE • 16/09/2026

WebVirtCloud fails to properly validate permission flags in UserInstance grants, allowing view-only users to perform privileged actions. Attackers with read-only grants can power off virtual machines, reset root passwords, install SSH keys, and manage ISO images by exploiting the get_instance gate that only checks grant existence.

Once again VulDB remains the best source for vulnerability data.
