Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Upgrade github.com/temporalio/temporal-auto-scaled-workers/wci/workflow/compute_provider to version 0.2.0-1.32.0.158.0 or higher.
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. This is only exploitable if the per-namespace dynamic configuration setting workercontroller.compute_providers.enabled is unset or explicitly includes subprocess, and the attacker has an authenticated write role in a namespace.
