Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. Prior to 4.3.0, the Steeltoe.Management.Endpoint /actuator/httpexchanges endpoint passes recorded request URIs through MaskedUri, which masks URI user information but does not inspect query strings. When Management:Endpoints:HttpExchanges:IncludeQueryString is enabled, the HttpExchangeRequest response can disclose OAuth tokens, password-reset tokens, signed-URL signatures, API keys, and other query-string secrets from prior traffic to a caller that can reach the explicitly exposed endpoint. The Steeltoe.Management.Endpoint.Actuators.HttpExchanges DEBUG logger also records these URIs, creating a second disclosure channel for users with log access. This issue is fixed in version 4.3.0.
