Fireshare has unauthenticated SSRF via missing login_required on webhook test endpoints
Source: CVE Program / CVE List V5
Vulnerability Description
Fireshare facilitates self-hosted media and link sharing. Prior to version 1.6.16, two API endpoints that trigger outbound HTTP requests are missing the @login_required decorator. An unauthenticated attacker can call POST /api/test-discord-webhook or POST /api/test-webhook and cause the Fireshare server to issue an arbitrary HTTP POST to any URL the attacker supplies, including internal network addresses and cloud metadata services. No credentials, session cookies, or prior access are required. Version 1.6.16 contains a patch.
