Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Temporal Server (go.temporal.io/server) versions before 1.20.0 are affected. An attacker who can create a task token outside the normal server flow, using the target namespace's UUID and workflow history information, can act on pending tasks in other namespaces, such as marking them failed or completed. Upgrade to version 1.20.0 or later. The source gives few details on any workaround.
