Executive brief
OpenViking is a code analysis and intelligence platform that processes various data sources. The vulnerability allows authenticated users with low privileges to make the server request arbitrary internal network addresses (including cloud metadata services and loopback interfaces), exposing sensitive information about internal infrastructure and potentially enabling access to services that should not be publicly reachable.
Technical details
This is a server-side request forgery (SSRF) vulnerability in the resources API endpoint (/api/v1/resources). Authenticated low-privilege attackers can POST crafted URLs to this endpoint, causing the server to issue outbound HEAD and GET requests with redirects enabled to private network ranges (RFC 1918), loopback addresses (127.0.0.1), link-local addresses, and cloud metadata services. The server response is readable through normal content APIs, allowing attackers to enumerate and interact with internal services. The vulnerability requires authentication but does not require admin/high privileges. A patch was released in version 0.3.4 that hardens HTTP resource ingestion with network request validation hooks to block requests to private/restricted address ranges.
