Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the OpenApiConverter process. An attacker can access internal network resources and sensitive metadata endpoints by supplying a malicious OpenAPI specification that declares a server URL pointing to internal or loopback addresses. This can result in exposure of internal services or credentials when the agent processes attacker-controlled URLs.
Workaround
This vulnerability can be mitigated by refusing to call registerManual with URLs controlled by untrusted parties and by restricting outbound network access from the host to prevent connections to internal addresses.
