CVE-2026-72597

EUVD-2026-56036
A server-side request forgery vulnerability in Friendica through the 2026.08-dev branch allows authenticated users with a free self-registered account to probe internal network services via the link-preview endpoint. The endpoint fetches any user-supplied URL without applying an internal IP deny list. An attacker can use this to scan the internal network or access cloud metadata services.
