Description
This security bulletin contains information about 1 security vulnerability.
1) Path traversal (CVE-ID: CVE-2025-54292)
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to improper input validation in URL path construction in lxd-ui when embedding user-controlled resource names in URL paths. A remote user can create a malicious resource name containing path traversal sequences to disclose sensitive information.
User interaction is required, and exploitation occurs when another user performs operations on the crafted resource, causing path normalization to switch to a different project or resource.
