Authenticated SSRF via unvalidated outbound request URLs
Published Mar 24, 2026 · Updated Mar 24, 2026
SSRF in ellite Wallos before 4.7.0 allows remote authenticated users to reach internal services through crafted AI or notification URLs. AI model endpoints and the notification cron job pass user-controlled or stored destination URLs to cURL without invoking the SSRF validator. A normal authenticated account is sufficient to probe internal hosts and access responses from reachable metadata or localhost services.
