Overview
Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs via the isVMLowLevelOptionForbidden function in lxd/project/limits/permissions.go. An attacker can set forbidden low-level VM configuration keys, such as raw.apparmor or raw.qemu.conf in a project that is supposed to block low-level options, allowing them to inject custom AppArmor or QEMU settings into a VM instance. This lets the attacker alter VM runtime behavior and weaken the isolation or control that the project’s limits are meant to enforce.
