SCA: security update for k8s.io/ingress-nginx (GHSA-4g2f-xcph-2335)

low Tenable Self-Hosted Container Security Plugin ID 437555

Description

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

 - A security issue was discovered in ingress-nginx where the protection afforded by the `auth-url` Ingress
 annotation may not be effective in the presence of a specific misconfiguration. If the ingress-nginx
 controller is configured with a default custom-errors configuration that includes HTTP errors 401 or 403,
 and if the configured default custom-errors backend is defective and fails to respect the X-Code HTTP
 header, then an Ingress with the `auth-url` annotation may be accessed even when authentication fails.
 Note that the built-in custom-errors backend works correctly. To trigger this issue requires an
 administrator to specifically configure ingress-nginx with a broken external component. (CVE-2026-24513)
