CVE-2026-75511
NVD: Novu provides an API for sending notifications through multiple channels. NVD: An authenticated user can supply an internal or otherwise restricted destination because these paths do not apply normalizeOutboundHttpUrl, assertSafeOutboundUrl, or the DNS-pinned safeOutboundJsonRequest protection used by the generic webhook providers. NVD: The Novu worker can consequently issue attacker-directed POST requests to internal network services and cause interactions or actions supported by those services.
