CVE-2025-46690
📋 TL;DR
Ververica Platform 2.14.0 contains an improper authorization vulnerability that allows low-privileged users to access SQL connectors they shouldn't have permission to use. This affects organizations running Ververica Platform 2.14.0 where user roles and permissions are configured. The vulnerability enables privilege escalation through direct API requests.
💻 Affected Systems
- Ververica Platform
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Low-privileged users could access sensitive SQL connectors, potentially exposing database credentials, executing unauthorized queries, or accessing restricted data sources.
Likely Case
Users with limited permissions could access SQL connectors beyond their intended scope, potentially viewing connector configurations or attempting unauthorized database operations.
If Mitigated
With proper network segmentation and strict access controls, impact would be limited to unauthorized connector viewing without actual database access.
🎯 Exploit Status
Exploitation requires authenticated access but minimal technical skill - simply accessing the direct API endpoint /namespaces/default/formats with low privileges.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 2.14.1 or later
Vendor Advisory: https://github.com/ververica/ververica-platform-playground
Restart Required: Yes
Instructions:
1. Backup current configuration. 2. Upgrade to Ververica Platform 2.14.1 or later. 3. Restart the Ververica Platform services. 4. Verify proper authorization is enforced.
🔧 Temporary Workarounds
Restrict API Access
linuxImplement network-level restrictions to limit access to the Ververica Platform API endpoints
# Use firewall rules to restrict access to Ververica API
iptables -A INPUT -p tcp --dport [VERVERICA_PORT] -s [TRUSTED_NETWORK] -j ACCEPT
iptables -A INPUT -p tcp --dport [VERVERICA_PORT] -j DROP
Temporary Role Review
allReview and temporarily restrict low-privileged user access to sensitive functionality
# Review current user roles and permissions
# Consider temporarily elevating minimum required permissions
# Monitor for unauthorized access attempts
🧯 If You Can't Patch
- Implement strict network segmentation to isolate Ververica Platform from sensitive databases
- Enhance monitoring of API access logs for suspicious patterns and implement alerting
🔍 How to Verify
Check if Vulnerable:
Attempt to access /namespaces/default/formats endpoint with a low-privileged user account. If successful, the system is vulnerable.Check Version:
Check Ververica Platform version via web interface or API, or review deployment configuration files for version information.Verify Fix Applied:
After patching, attempt the same access with low-privileged user - should receive authorization error or be denied access.📡 Detection & Monitoring
Log Indicators:
- Unauthorized access attempts to /namespaces/default/formats endpoint
- SQL connector access by low-privileged users
- Authorization failures followed by successful access
Network Indicators:
- HTTP GET requests to /namespaces/default/formats from unauthorized IPs or users
- Unusual database connection attempts following API access
