CVE-2026-63295

Medium
Open
TLP:CLEAR

Project restriction `restricted.containers.privilege=isolated` bypassable by omitting `security.idmap.isolated`

AI Analysis

No AI analysis yet.

Description

An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass project-level container isolation restrictions. When a project is configured with restrictions on container privileges (such as enforcing restricted.containers.privilege=isolated), LXD fails to enforce the requirement if an instance configuration omits the security.idmap.isolated key. An attacker can exploit this flaw by creating or updating an instance without explicitly setting security.idmap.isolated, bypassing the target project's security constraints.
