Authenticated internal-service disclosure via notification test SSRF

Published Sep 18, 2026 · Updated Sep 18, 2026

SSRF in OpenCVE before 3.0.0 allows remote authenticated users to read responses from internal HTTP services through notification tests. The notification Try flow passes a user-controlled webhook or Slack URL and headers to an unrestricted HTTP POST, then renders the full response. Any registered user who owns an organization can reach the flow, exposing localhost, private-network, link-local, and cloud-metadata responses.
