CVE-2026-53751 dataease CVE debrief

Who should care

Users of DataEase open source data visualization and analysis tool versions prior to 2.10.24 should apply the patch to prevent arbitrary code execution. Affected operators, platforms, vulnerability-management, and security teams should review the vulnerability and take necessary actions. The vulnerability has a high CVSS score, and users should prioritize patching to prevent exploitation.

Technical summary

The H2 database JDBC URL validation logic in DataEase can be bypassed with special Unicode characters whose case-conversion behavior differs between DataEase validation and H2 parsing. This allows attackers to smuggle dangerous parameters, such as 'init', in malicious H2 JDBC connection strings and achieve arbitrary code execution. The vulnerability is fixed in version 2.10.24, and users should apply the patch to prevent exploitation.

Defensive priority

High priority should be given to patching DataEase installations to version 2.10.24 or later to prevent exploitation of this vulnerability. Additional defensive measures, such as monitoring and compensating controls, should be reviewed and implemented to prevent exploitation.

Recommended defensive actions

• Apply the patch by updating DataEase to version 2.10.24 or later
• Review and validate H2 database JDBC URL connections
• Monitor for suspicious activity and anomalies in DataEase usage
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented

Evidence notes

The CVE record was published on 2026-07-07T21:17:26.857Z and has not been modified since then. The NVD entry is currently being reviewed. Evidence limits suggest that further verification is needed to confirm affected scope and severity. Defenders should verify H2 database JDBC URL validation logic and special Unicode characters. Limited source detail is available, and additional review is required.
