Impact
Polyaxon through 2.16.4 renders operation specification fields with an unsandboxed Jinja2 environment during server-side run preparation, allowing authenticated users to execute arbitrary code. Attackers can submit runs with Jinja2 payloads in queue, namespace, conditions, presets, or dependencies fields to execute operating system commands in the scheduler process context, exposing database credentials and service tokens.
