Command Injection

Overview Affected versions of this package are vulnerable to Command Injection via the subprocess compute provider in the Worker Controller Instance module. An attacker can execute arbitrary commands on the Worker Service host by supplying a crafted compute provider configuration in their request...

Unchecked Input for Loop Condition

Overview Affected versions of this package are vulnerable to Unchecked Input for Loop Condition due to unbounded next-action-time search in the schedule spec evaluation logic in service/worker/scheduler/spec.go and the scheduler/frontend list-matching-time paths. An authenticated caller with...

CVE-2026-89139

Temporal Server compiles a Worker Controller Instance module into its Worker Service, and that module registers a compute provider named subprocess whose function is to launch a worker by running a command on the machine hosting the Worker Service. The program name and the argument vector that...

CVE-2026-87858

Temporal Server decided whether a Workflow completion callback was internal by reading a caller-supplied HTTP header. An authenticated caller holding only write permission in a single namespace could attach a completion callback whose URL host matched the configured callback address allowlist,...

CVE-2026-16652

Temporal Server did not bound the work performed while searching for a Schedule's next action time. An authenticated caller with namespace write permission could create or update a Schedule that combines a fine-grained cadence with an exclusion calendar that rejects every candidate time, causing...
