CVE-2025-14986Network attack vector

Authenticated policy bypass via mismatched namespace validation

Published Dec 30, 2025 · Updated Dec 30, 2025

Incorrect authorization in Temporal Technologies' Temporal 1.24.0 through 1.29.1 allows remote authenticated users to bypass namespace policies. ExecuteMultiOperation validates the embedded StartWorkflowExecutionRequest.Namespace instead of the authorized outer request namespace, so crafted input selects another namespace's limits and feature gates. The gate is frontend.enableExecuteMultiOperation; workflows remain in the authorized outer namespace, but their validation and policy context can be altered.
