CVE-2025-25209
📋 TL;DR
This vulnerability in Red Hat Connectivity Link allows developers with access to leak secrets via HTTP connections. The AuthPolicy metadata incorrectly assumes secrets are already in the kuadrant-system namespace instead of copying them to the referred namespace. This affects Red Hat Connectivity Link deployments where developers have access to the vulnerable component.
💻 Affected Systems
- Red Hat Connectivity Link
⚠️ 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
Sensitive secrets (API keys, passwords, tokens) are exposed to unauthorized developers, leading to data breaches, privilege escalation, or lateral movement within the cluster.
Likely Case
Developers with access to the vulnerable component can read secrets they shouldn't have access to, potentially exposing credentials for other services.
If Mitigated
With proper namespace isolation and RBAC controls, only authorized users can access secrets, limiting exposure.
🎯 Exploit Status
Exploitation requires authenticated developer access and knowledge of specific secret names that are limited to one line.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Red Hat advisory for specific patched versions
Vendor Advisory: https://access.redhat.com/security/cve/CVE-2025-25209
Restart Required: Yes
Instructions:
1. Check Red Hat advisory for patched versions. 2. Update Red Hat Connectivity Link to patched version. 3. Restart affected components. 4. Verify secrets are properly copied to referred namespaces.
🔧 Temporary Workarounds
Restrict Developer Access
linuxLimit developer access to AuthPolicy metadata and secrets using RBAC controls
kubectl create rolebinding restrict-authpolicy --role=view --user=developer --namespace=kuadrant-system
Audit Secret Usage
linuxReview and remove unnecessary secrets from AuthPolicy metadata
kubectl get authpolicy -o yaml | grep -A5 -B5 'secrets:'
🧯 If You Can't Patch
- Implement strict RBAC controls to limit who can access AuthPolicy metadata
- Regularly audit and rotate secrets stored in AuthPolicy metadata
🔍 How to Verify
Check if Vulnerable:
Check if AuthPolicy metadata references secrets that aren't properly copied to the referred namespace: kubectl get authpolicy -o yaml | grep -A10 'secrets:'Check Version:
Check Red Hat Connectivity Link version via cluster management tools or kubectl get deployments -n kuadrant-systemVerify Fix Applied:
Verify secrets are properly copied to referred namespaces and developer access is restricted📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to AuthPolicy endpoints
- Unusual HTTP requests to secret-related endpoints
Network Indicators:
- HTTP requests to AuthPolicy metadata endpoints from unauthorized sources
