k8s.io/ingress-nginx fixed: 1.13.7 
Upgrade k8s.io/ingress-nginx to 1.13.7
k8s.io/ingress-nginx fixed: 1.14.3 
Upgrade k8s.io/ingress-nginx to 1.14.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for k8s.io/ingress-nginx

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-24514, inspect your project dependencies for K8s.io/ingress nginx:

inspect dependencies for k8s.io/ingress-nginx

Analyze the terminal output to locate any version of K8s.io/ingress nginx in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.13.7), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In K8s.io/ingress nginx, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A security issue was discovered in ingress-nginx where the validating admission controller feature is subject to a denial of service condition. By sending large requests to the validating admission controller, an attacker can cause memory consumption, which may result in the ingress-nginx controller pod being killed or the node running out of memory.
