Detailsinfo

A vulnerability, which was classified as problematic, was found in volcano-sh volcano up to 1.12.3/1.13.2/1.14.1. This affects an unknown part of the component Webhook Endpoint. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-44247 since 05/05/2026. The exploitability is told to be easy. The attack needs to be done within the local network. Neither technical details nor an exploit are publicly available.

Upgrading to version 1.12.4, 1.13.3 or 1.14.2 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2026-32666). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
