CVE-2026-24816
📋 TL;DR
This CVE describes an infinite loop vulnerability in the ChangeDomainAction.java component of the datavane TIS platform. Attackers could trigger this condition to cause denial of service by consuming excessive CPU resources. This affects all TIS deployments running versions before 4.3.0.
💻 Affected Systems
- datavane TIS (tis-console)
⚠️ 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).

- 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 service unavailability due to CPU exhaustion, potentially affecting all functionality of the TIS platform
Likely Case
Degraded performance or temporary service disruption for affected components
If Mitigated
Minimal impact with proper resource limits and monitoring in place
🎯 Exploit Status
Exploitation requires access to trigger the vulnerable ChangeDomainAction functionality
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 4.3.0 and later
Vendor Advisory: https://github.com/datavane/tis/pull/444
Restart Required: Yes
Instructions:
1. Upgrade TIS to version 4.3.0 or later
2. Restart the TIS application server
3. Verify the fix by checking the version and testing affected functionality
🔧 Temporary Workarounds
Implement resource limits
allSet CPU and memory limits on the TIS application container/process
# For Docker: docker run --cpus="1.0" --memory="512m" ...
# For systemd: add CPUQuota=100% and MemoryLimit=512M in service file
Restrict access to vulnerable endpoints
linuxLimit network access to the TIS console endpoints
# Example firewall rule: iptables -A INPUT -p tcp --dport <tis-port> -s <trusted-networks> -j ACCEPT
🧯 If You Can't Patch
- Implement strict access controls to limit who can trigger the ChangeDomainAction functionality
- Deploy monitoring and alerting for abnormal CPU usage patterns that might indicate exploitation
🔍 How to Verify
Check if Vulnerable:
Check TIS version and compare against affected versions (< 4.3.0)Check Version:
Check application logs or configuration files for version information, or query the TIS API if availableVerify Fix Applied:
Confirm TIS version is 4.3.0 or later and test the ChangeDomainAction functionality📡 Detection & Monitoring
Log Indicators:
- Repeated error messages from ChangeDomainAction
- High CPU usage alerts
- Application thread dumps showing stuck threads
Network Indicators:
- Unusual number of requests to ChangeDomainAction endpoints
- Increased network traffic to TIS console
SIEM Query:
source="tis-logs" AND (message="*ChangeDomainAction*" OR thread_state="RUNNABLE" AND cpu_usage>90)
