CVE-2026-79754 Details
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.
A command injection vulnerability has been identified in Nuclio's Dashboard build pipeline, specifically in versions 1.6.19 prior to 1.17.2. The issue arises because the 'spec.build.tempDir' field is not properly sanitized before being used to create a shell command. When the Kaniko container builder is enabled, this flaw allows a user with function-create permission to inject shell metacharacters, leading to arbitrary command execution within the Dashboard container. This container operates under a Kubernetes service account with broad access to Secrets, Pods, Jobs, and Deployments within its namespace.
Users can upgrade to Nuclio version 1.17.2 or later, where this vulnerability has been patched.
