OpenCVE is a vulnerability intelligence platform. Prior to 3.0.0, OpenCVE notification testing for Webhook and Slack integrations does not sufficiently validate user-supplied HTTP or HTTPS destinations. An authenticated user with permission to configure notification channels can trigger requests to hosts reachable from the OpenCVE server, including internal network resources, localhost interfaces, link-local addresses, and cloud metadata services, and retrieve information from reachable HTTP services.
This issue is fixed in version 3.0.0.
