SCA: security update for volcano.sh/volcano (GHSA-8wxp-xxp2-rcgx)

high Tenable Cloud Security Plugin ID 441591

Description

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

 - Volcano is a Kubernetes-native batch scheduling system. Prior to v1.14.2, v1.13.3, and v1.12.4, the
 Volcano webhook server does not enforce a size limit on incoming HTTP request bodies. Any in-cluster pod
 that can reach the webhook endpoint may send an arbitrarily large request body, potentially causing the
 webhook server to be killed by OOM. All Volcano deployments with the webhook server exposed to in-cluster
 traffic are affected. This vulnerability is fixed in v1.14.2, v1.13.3, and v1.12.4. (CVE-2026-44247)

Solution

Update the volcano.sh/volcano library and its related packages to version 1.12.4 or later.
