High (8.0). EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/nuclio/nuclio 0.0.0-20260601075854-3356b86a8bfa.
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.16.4, the Nuclio controller builds a curl invocation string for each cron trigger and stores it as the args of a Kubernetes CronJob container (/bin/sh, -c, <command>). Two fields in the trigger specification flow into this string without adequate sanitization: event.headers keys and event.body. This issue has been patched in version 1.16.4.
