Machine-written summary

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

GHSA-992g-9cr3-vm5x affects the Hatchet Go package github.com/hatchet-dev/hatchet before version 0.106.1, where the DurableTask gRPC WorkerStatus path accepts a caller-supplied durable task UUID and returns event-log entries without a tenant check. An attacker holding a valid API token for one tenant would need to guess or otherwise obtain another tenant's task UUID, which is hard given UUID v4 randomness, to read that data. Upgrade to Hatchet 0.106.1 or later.
