{"id":"CVE-2025-1243","state":"PUBLISHED","title":"Field in api-go proxy not transformed before version 1.44.1","description":"The Temporal api-go library prior to version 1.44.1 did not send `update response` information to Data Converter when the proxy package within the api-go module was used in a gRPC proxy prior to transmission. This resulted in information contained within the `update response` field not having Data Converter transformations (e.g. encryption) applied. This is an issue only when using the UpdateWorkflowExecution APIs (released on 13th January 2025)  with a proxy leveraging the api-go library before version 1.44.1.\n\nOther data fields were correctly sent to Data Converter. This issue does not impact the Data Converter server. Data was encrypted in transit.
