# OpenKruise kruise-manager: unauthenticated pprof endpoint enables denial of service

When enabled, OpenKruise's kruise-manager listens on 0.0.0.0:8090 with an unauthenticated pprof endpoint. Any pod with RBAC access can trigger it to cause a denial of service.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check whether the pprof endpoint is enabled in the kruise-manager configuration and whether port `8090` is exposed on `0.0.0.0`
- Confirm the installed OpenKruise version against the fixed release in the sources: unknown

## Fix

- Fixed version: unknown
- Upgrade to the release referenced in the vendor release notes: unknown

## Timeline

- 2026-11-02T19:24:40+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-120656

## Documents

- [fix] Release notes: github.com https://github.com/openkruise/kruise/releases/tag/v1.9.2

## From the sources

OpenKruise kruise-manager exposes an unauthenticated ppof endpoint when enabled, opening it on 0.0.0.0:8090, which can enable a DoS attack triggerable by any RBAC pod.
