CVE-2026-45534 dataease CVE debrief

Who should care

Users of DataEase versions prior to 2.10.23 who utilize Redshift datasource connections should be aware of this critical vulnerability and take immediate action to upgrade to the patched version. This includes operators, platform administrators, vulnerability management teams, and security teams who need to review and mitigate this vulnerability.

Technical summary

The vulnerability exists in DataEase Redshift datasource connections due to the loading of attacker-controlled rsjdbc.ini configuration from System.getProperty('java.io.tmpdir'). This allows for the execution of a reflection-based remote code execution chain during a normal JDBC connection through io.dataease.datasource.type.Redshift. The issue is fixed in version 2.10.23. Affected users should verify their deployments, review official advisories for affected scope and vendor guidance, and take immediate action to upgrade to the patched version to mitigate this critical vulnerability.
