Last modified

CVE-2026-13303 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. HashiCorp Boundary and Boundary Enterprise are vulnerable to a server-side request forgery in the Vault credential store integration that may allow an authenticated user with permission to manage credential stores and credential libraries within a project to cause the Boundary controller to issue outbound requests to a network destination of the requester's choosing and to receive the response. This may expose endpoints reachable only from the controller's host, such as a cloud instance metadata service. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
