CVE-2025-14987 is a medium-severity vulnerability affecting Temporal Server versions through 1.29.1, where the default setting "system.enableCrossNamespaceCommands" allows a worker authorized for one namespace to execute workflow task commands (e.g., StartChildWorkflowExecution) in a different, unauthorized namespace. This bypasses gRPC boundary authorization, potentially leading to unauthorized creation, signaling, or cancellation of workflows. The CVSS score is 5.3 MEDIUM, indicating low attack complexity and potential for limited impact on confidentiality, integrity, and availability. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
