SCA: security update for github.com/fission/fission (GHSA-qf5v-m7p4-95rp)

high Tenable Self-Hosted Container Security Plugin ID 445444

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, Fission added PodSpec safety validation
 for tenant-facing Environment and Function CRDs (ValidatePodSpecSafety / ValidateContainerSafety admission
 webhook + sanitizeContainerSecurityContext executor merge layer), but the capability check was implemented
 as a fixed denylist of six Linux capabilities (SYS_ADMIN, NET_ADMIN, SYS_PTRACE, SYS_MODULE,
 DAC_READ_SEARCH, DAC_OVERRIDE). The denylist omitted CAP_SYS_TIME, among others. As a result, a tenant who
 could create a Function or Environment CRD could request securityContext.capabilities.add: ["SYS_TIME"],
 pass Fission's admission validation and merge-layer sanitization, and run attacker-controlled code with
 CAP_SYS_TIME in the resulting function or runtime container. This issue has been patched in version
 1.25.0. (CVE-2026-50570)

Solution

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