A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Users should consider disabling the ppof endpoint if not needed or restricting network access to port 8090.

Description

OpenKruise's kruise-manager component exposes an unauthenticated ppof endpoint on all network interfaces (0.0.0.0) at port 8090 when enabled. This exposure allows any pod with RBAC permissions to trigger a denial-of-service (DoS) attack against the service.

Impact

The impact is a denial-of-service condition triggered by unauthenticated access to the ppof endpoint. Any pod with RBAC permissions can exploit this to disrupt the kruise-manager service. There is no indication of privilege escalation or data compromise from the provided information.

Summary

The vulnerability in OpenKruise's kruise-manager arises from an unauthenticated ppof endpoint that listens on 0.0.0.0:8090 when enabled. This endpoint does not require authentication, enabling any pod with RBAC permissions to invoke it and potentially cause a denial-of-service condition. No CVSS score or detailed exploit information is provided, and no affected versions or patches are specified.
