CVE-2026-28385Public exploitNetwork attack vector

Internal network probing via unrestricted image import

Published Jun 26, 2026 · Updated Jun 26, 2026

SSRF in Canonical LXD 4.0.0 through 6.9 allows remote authenticated users to probe internal services through image imports. The imgPostURLInfo path sends HEAD requests to attacker-supplied URLs through a dialer that permits private, loopback, and link-local addresses and follows redirects without revalidating their destinations. The can_create_images entitlement is required; differentiated operation errors reveal reachability and port state, while response-body hash validation blocks direct content exfiltration.
