SCA: security update for github.com/fission/fission (GHSA-7pjr-qpvh-m339)

medium Tenable Cloud Security Plugin ID 442286

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Fission is an open-source, Kubernetes-native serverless framework that simplifies the deployment of
 functions and applications on Kubernetes. Prior to version 1.23.0, before the round-1 security sweep,
 pkg/builder/builder.go passed Environment.spec.builder.command directly into exec.Command(...) after a
 strings.Fields split, with no validation of the executable path or its arguments. A user who could create
 or update Environment CRDs in a namespace observed by the buildermgr could thereby point the builder pod
 at any executable inside the builder image (e.g. /bin/sh -c '...') and execute arbitrary code in the
 builder pod context. This issue has been patched in version 1.23.0. (CVE-2026-46618)

Solution

Update the github.com/fission/fission library and its related packages to version 1.23.0 or later.
