Summary
OpenKruise PodProbeMarker is Vulnerable to SSRF via Unrestricted Host Field
Impact
Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside. Typical impact: access to internal metadata services, internal APIs, or cloud credentials.
Affected versions
Security releases
Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Temporary mitigation:
- Restrict PodProbeMarker creation permissions
- Apply network policies limiting kruise-daemon egress
- Audit existing PodProbeMarker resources
Permanent fix:
- Enforce Host field restrictions in webhook validation
- Deny private IP ranges (127.0.0.0/8, 10.0.0.0/8, 169.254.0.0/16)
- Require Host to be empty or equal to PodIP
- Sanitize error messages in NodePodProbe status
Verification Environment: kind v1.30.0 + OpenKruise v1.8.0
Frequently Asked Questions
- What is CVE-2026-24005? CVE-2026-24005 is a low-severity server-side request forgery (SSRF) vulnerability in github.com/openkruise/kruise (go), affecting versions >= 1.8.0, < 1.8.3. It is fixed in 1.8.3, 1.7.5. Untrusted input controls the target URL of a server-initiated request, which may reach internal services not otherwise accessible from outside.
- Which versions of github.com/openkruise/kruise are affected by CVE-2026-24005? github.com/openkruise/kruise (go) versions >= 1.8.0, < 1.8.3 is affected.
- Is there a fix for CVE-2026-24005? Yes. CVE-2026-24005 is fixed in 1.8.3, 1.7.5. Upgrade to this version or later.
- Is CVE-2026-24005 exploitable, and should I be worried? Whether CVE-2026-24005 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-24005 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
