SCA: security update for github.com/fission/fission (GHSA-q6vm-xqc9-v3ff)

high Tenable Self-Hosted Container Security Plugin ID 445440

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 1.25.0, Unarchive in pkg/utils/zip.go joined
each archive entry name with the destination directory via filepath.Join and wrote the result without
checking whether the resolved path stayed under the destination. A zip entry named ../../tmp/evil
therefore landed at /tmp/evil. An attacker who could control a Package.Spec.Source.URL or Deployment.URL
archive could induce the fetcher (running as the per-environment pod's fission-fetcher sidecar) to write
files anywhere that process could reach: into other tenants' /packages/<ns>/ directories, into mounted
secret/config volumes, or into the fetcher's own binary. This issue has been patched in version 1.25.0.
(CVE-2026-50567)

Solution

Update the github.com/fission/fission library and its related packages to version 1.25.0 or later.
