CVE-2026-45534
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDataEase is an open source data visualization and analysis tool. Prior to 2.10.23, DataEase Redshift datasource connections can load attacker-controlled rsjdbc.ini configuration from System.getProperty("java.io.tmpdir"), setting socketFactory=org.springframework.context.support.FileSystemXmlApplicationContext so com.amazon.redshift.Driver#connect, com.amazon.redshift.Driver#getJdbcIniFile, and com.amazon.redshift.util.ObjectFactory#instantiate execute a reflection-based remote code execution chain during a normal JDBC connection through io.dataease.datasource.type.Redshift. This issue is fixed in version 2.10.23.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDataEase versions prior to 2.10.23 have a path traversal vulnerability in the Redshift datasource connector. The connector loads the rsjdbc.ini configuration file from java.io.tmpdir without validation, allowing attackers to place a malicious ini file that specifies a Spring FileSystemXmlApplicationContext as socketFactory. During normal JDBC connection through io.dataease.datasource.type.Redshift, the com.amazon.redshift.Driver#connect and related methods instantiate this attacker-controlled class via reflection, achieving remote code execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify DataEase installation and versionLocate the DataEase installation directory and find its version information (typically in a version file, about page, or pom.xml within the application). Compare your installed version against the fixed version 2.10.23.Affected if DataEase version is lower than 2.10.23 and the Redshift connector is in use.
-
Confirm Redshift datasource connector is configuredReview DataEase datasource configurations to determine if a Redshift (Amazon Redshift) datasource has been created or is active in the environment.Affected if A Redshift datasource is configured or was recently used in DataEase.
-
Inspect java.io.tmpdir for rsjdbc.ini filesExamine the Java temporary directory (java.io.tmpdir, often /tmp or a Windows temp folder) for any rsjdbc.ini files. List all files matching this name.Affected if An rsjdbc.ini file exists in the temp directory and contains attacker-controlled socketFactory or other malicious configuration.
-
Verify temp directory write permissionsCheck file system permissions on the java.io.tmpdir directory to determine if unprivileged users or processes can write files to this location.Affected if The temp directory is world-writable or writable by untrusted users, allowing placement of a malicious rsjdbc.ini file.
If DataEase version is below 2.10.23, the Redshift connector is active, and the temp directory either contains an rsjdbc.ini file with malicious socketFactory settings or is writable by attackers, the environment is vulnerable to CVE-2026-45534.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade DataEase to version 2.10.23 or later. Additionally, restrict write access to the temporary directory and monitor for unauthorized rsjdbc.ini files.
DataEase version 2.10.23
- 1. Back up your current DataEase installation and database
- 2. Download DataEase version 2.10.23 from the official GitHub releases page (github.com/dataease/dataease)
- 3. Stop the DataEase service
- 4. Install version 2.10.23 following the standard upgrade procedure for your deployment method
- 5. Start the DataEase service
- 6. Verify the Redshift datasource connector works correctly in version 2.10.23
- 7. Confirm the vulnerability is remediated by testing a Redshift connection
