CVE-2026-92789 PUBLISHED

Graylog through 7.1.4 Server-Side Request Forgery via HTTP Redirect

Assigner: VulnCheck
Reserved: 16.09.2026 Published: 16.09.2026 Updated: 16.09.2026

Graylog through 7.1.4 validates outbound URLs against an allowlist before making requests but fails to re-validate after following HTTP redirects. Attackers with lookup table or event notification permissions can craft allowlisted endpoints that redirect to internal services, enabling the server to fetch and return internal responses.
