Uncontrolled Recursion Affecting github.com/go-openapi/swag/jsonutils/adapters/easyjson/json package, versions <0.27.1
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

NewCVE-2026-93450 (opens in a new tab)How to fix?
Upgrade github.com/go-openapi/swag/jsonutils/adapters/easyjson/json to version 0.27.1 or higher.
Overview
Affected versions of this package are vulnerable to Uncontrolled Recursion in the ordered-JSON marshal/unmarshal paths through the jsonutils/adapters/stdlib/json and jsonutils/adapters/easyjson/json ordered map handlers. An attacker can crash the process by sending a deeply nested JSON document to ReadJSON/JSONMapSlice.UnmarshalJSON or by causing WriteJSON/JSONMapSlice.MarshalJSON to process an equally deep in-memory JSONMapSlice. The unbounded recursion exhausts the goroutine stack and triggers a non-recoverable fatal error: stack overflow, terminating the serving process and dropping in-flight requests.
