Summary

go-openapi/swag jsonutils before 0.27.1 contains a stack overflow vulnerability in ordered JSON parsing and serialization due to unbounded recursion with no depth limit. Remote unauthenticated attackers can submit deeply nested JSON documents to services accepting OpenAPI specifications, causing fatal stack overflow that terminates the process and all in-flight requests.

Risk Assessment

The risk includes denial of service (DoS) via remote stack overflow, potentially leading to application unavailability for users.

Recommendation

Upgrade go-openapi/swag jsonutils to version 0.27.1 or later, which introduces a recursion depth limit.
