Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.71%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. From version 1.6.19 to before version 1.17.2, Nuclio's Dashboard build pipeline does not sanitize the spec.build.tempDir field before using it to construct a shell command. When the Kaniko container builder is enabled, a user with function-create permission can inject shell metacharacters into this field and achieve arbitrary command execution inside the Dashboard container, which runs with a Kubernetes service account holding wildcard access to Secrets, Pods, Jobs, and Deployments in its namespace. This issue has been patched in version 1.17.2.
