SCA: security update for github.com/fission/fission (GHSA-gx55-f84r-v3r7)

critical Tenable Cloud Security Plugin ID 444148

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 1.24.0, Fission's Environment CRD exposes
 spec.runtime.podSpec and spec.builder.podSpec, which are merged into the Kubernetes pod specs for runtime
 and builder pods. The merge logic propagated hostNetwork, hostPID, hostIPC, container privileged, and
 serviceAccountName from the user-supplied podspec with no filtering, and Environment.Validate performed no
 security-relevant checks on these fields. This issue has been patched in version 1.24.0. (CVE-2026-50564)

Solution

Update the github.com/fission/fission library and its related packages to version 1.24.0 or later.
