EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.0 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 80% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In Canonical LXD versions 4.12 through 6.9, a Server-Side Request Forgery (SSRF) vulnerability in the image import functionality allows authenticated users with the can_create_images entitlement to interact with internal network infrastructure via the /images endpoint. When importing an image from a URL source, the LXD daemon fails to validate or restrict outbound destination IP addresses, allowing connections to loopback, RFC1918 private ranges, and cloud metadata endpoints. This enables error-based port scanning and unauthorized interaction with internal HTTP services from the daemon's network position.
