CVE-2025-14443
📋 TL;DR
This SSRF vulnerability in OpenShift's API server allows attackers to make the server send requests to internal network resources by manipulating image references. It enables internal network scanning, service discovery, information disclosure, and potential DoS attacks. All OpenShift deployments using the vulnerable ose-openshift-apiserver component are affected.
💻 Affected Systems
- OpenShift Container Platform
- Red Hat OpenShift
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete internal network mapping, credential theft from metadata services, denial of service to critical internal services, and potential lateral movement to other systems.
Likely Case
Internal service enumeration, limited information disclosure from internal endpoints, and resource exhaustion leading to performance degradation.
If Mitigated
Limited impact due to network segmentation, egress filtering, and proper authentication requirements for internal services.
🎯 Exploit Status
Proof-of-concept available on GitHub; requires some user privileges but exploitation is straightforward
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisory for specific fixed versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2025-14443
Restart Required: Yes
Instructions:
1. Check current OpenShift version
2. Apply Red Hat security updates via yum update
3. Restart ose-openshift-apiserver pods
4. Verify patch application
🔧 Temporary Workarounds
Network egress filtering
linuxRestrict outbound connections from OpenShift API server to only necessary external registries
# Configure network policies to limit egress
oc apply -f network-policy.yaml
Image reference validation
linuxImplement admission webhooks to validate image references before processing
# Deploy custom admission controller
oc apply -f admission-webhook.yaml
🧯 If You Can't Patch
- Implement strict network segmentation to isolate OpenShift API server from sensitive internal networks
- Deploy Web Application Firewall (WAF) with SSRF protection rules
🔍 How to Verify
Check if Vulnerable:
Check if your OpenShift version matches affected versions in Red Hat advisoryCheck Version:
oc get pods -n openshift-apiserver -o jsonpath='{.items[*].spec.containers[*].image}' | grep openshift-apiserverVerify Fix Applied:
Verify ose-openshift-apiserver image version after update and test SSRF attempts are blocked📡 Detection & Monitoring
Log Indicators:
- Unusual outbound connections from API server
- Failed image pull attempts to internal IPs
- SSRF pattern in API server logs
Network Indicators:
- API server making requests to internal RFC1918 addresses
- Unexpected connections to metadata services (169.254.169.254)
SIEM Query:
