Vulnerability from cvelistv5 – Published: 2026-08-11 11:13 – Updated: 2026-08-11 12:14

Title

Friendica Friendica - Server-Side Request Forgery

Summary

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.

Severity

6.5 (Medium)
