  "summary" : "Steeltoe.Management.Endpoint: HttpExchanges URI masking leaks query-string secrets",
  "details" : "## Summary\n\nSteeltoe's `/actuator/httpexchanges` endpoint records and displays request URIs after passing them through `MaskedUri`. The masking only covers the `UserInfo` portion of the URI (inline `user:password@host` credentials) and does not inspect the query string. With `IncludeQueryString` enabled by default, any secrets carried in query strings (for example: OAuth tokens, password-reset tokens, signed-URL signatures, API keys) are returned verbatim in the `uri` field of the response and written to logs at DEBUG level.\n\n## Impact\n\nAny caller who can reach `/actuator/httpexchanges` can receive full request URIs from prior traffic, including any secrets those URIs contained in their query strings. Applications with DEBUG-level logging enabled for the `Steeltoe.Management.Endpoint.Actuators.HttpExchanges` namespace also write these URIs to their application logs.\n\n## Affected configuration\n\n- `httpexchanges` is explicitly added to the actuator exposure list (`Management:Endpoints:Web:Exposure:Include`). It is not included by default.\n- The application handles requests that carry secrets in query strings, such as OAuth callbacks, signed URLs, or password-reset links.\n- DEBUG logging is enabled for `Steeltoe.Management.Endpoint.Actuators.HttpExchanges` (log exposure only).\n\n## Mitigations\n\nIf an immediate upgrade is not possible:\n\n- Remove `httpexchanges` from the actuator exposure list, or restrict it behind authentication.\n- Set `Management:Endpoints:HttpExchanges:IncludeQueryString` to `false` to strip query strings from recorded exchanges entirely.",
