Authenticated intranet disclosure via notification SSRF

Published Jun 12, 2026 · Updated Jun 12, 2026

SSRF in NezhaHQ Nezha Monitoring 1.4.0 through 2.0.7 allows remote authenticated users to read intranet HTTP response bodies. The member-accessible notification create and update handlers pass a user-controlled URL to Send(), which issues the request and embeds each unbounded non-2xx body in the API error response. A RoleMember account is required, and access is limited to HTTP content reachable from the Dashboard host.
