Vulnerability Title
Cross-project instance copy bypasses target project restrictions via TOCTOU in config merge
Vulnerability Description
An authorization bypass vulnerability in LXD due to a timing flaw during configuration merging allows an authenticated attacker to bypass target project restrictions during cross-project instance copies. When copying an instance to a target project, LXD performs restriction checks before configuration merging is complete, creating a time-of-check to time-of-use (TOCTOU) condition. An attacker can exploit this flaw to copy instances with disallowed high-privilege configurations into restricted projects, bypassing security controls.

Vulnerability Title
Canonical LXD 竞争条件问题漏洞
Vulnerability Description
Canonical LXD是英国Canonical公司开源的一款基于Linux系统用于管理应用程序的容器。 Canonical LXD 5.0.8之前版本和5.21.6之前版本存在安全漏洞,该漏洞源于配置合并期间存在时间差,导致检查时间与使用时间不一致,可能允许经过身份验证的攻击者绕过目标项目限制,将高权限配置的实例复制到受限项目,绕过安全控制。
