Details

OpenViking before 0.3.4 contains a server-side request forgery vulnerability that allows authenticated low-privilege attackers to access internal network services by submitting arbitrary URLs to the resources API endpoint. Attackers can POST a crafted URL to /api/v1/resources, causing the server to issue outbound HEAD and GET requests with redirects enabled to loopback, RFC 1918, link-local, or cloud metadata addresses, then read back responses through normal content APIs to enumerate and interact with internal services.

Severity
8.5 (High)
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N
8.3 (High)
CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:N/SA:N
