Steeltoe is an open source project that provides a collection of libraries that helps users build cloud-native applications. In Steeltoe.Management.Endpoint prior to version 4.2.0 and Steeltoe.Management.EndpointCore prior to version 3.4.0, the
Sanitizer component in the Environment actuator redacts configuration values by matching the configuration key name against a suffix list. The default list (password, secret, key, token, .*credentials.*, vcap services) does not cover the standard .NET pattern ConnectionStrings:<name> or Steeltoe Connectors' Steeltoe:Client:<type>:Default:ConnectionString. There is no value-based scrubbing, so full connection string values including embedded Password= and user:pass@host segments are returned verbatim in /actuator/env responses. Steeltoe.Management.Endpoint 4.2.0 and Steeltoe.Management.EndpointCore 3.4.0 patch the issue. If an immediate upgrade is not possible: On the standard path, remove env from the actuator exposure list; add .*connectionstring.* to KeysToSanitize as a defense-in-depth measure for both paths; and/or require authorization on actuator endpoints.Fix
