CVE-2026-50200 (opens in a new tab)How to fix?
Upgrade Steeltoe.Management.EndpointCore to version 3.4.0 or higher.
Overview
Affected versions of this package are vulnerable to Cleartext Transmission of Sensitive Information in the Sanitizer function of the Environment actuator, which fails to redact sensitive information from configuration keys matching standard .NET patterns such as ConnectionStrings:<name> or Steeltoe Connectors' Steeltoe:Client:<type>:Default:ConnectionString. An attacker can obtain embedded database credentials by accessing the /actuator/env endpoint and retrieving unredacted connection string values.
Workaround
This vulnerability can be mitigated by removing env from the actuator exposure list, adding .*connectionstring.* to KeysToSanitize, and/or requiring authorization on actuator endpoints.
