CVE-2025-49003
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 business intelligence and data visualization tool. Prior to version 2.10.11, a threat actor may take advantage of a feature in Java in which the character "ı" becomes "I" when converted to uppercase, and the character "ſ" becomes "S" when converted to uppercase. A threat actor who uses a carefully crafted message that exploits this character conversion can cause remote code execution. The vulnerability has been fixed in v2.10.11. No known workarounds are available.
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 2.10.11 contain a Remote Code Execution vulnerability exploiting Java's locale-specific character conversion behavior, where the Turkish characters 'ı' (dotless i) converts to 'I' and 'ſ' (long s) converts to 'S' when using toUpperCase(). Attackers craft malicious input leveraging this conversion to bypass authentication or input validation and achieve RCE.

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.
-
Check installed DataEase versionAccess the DataEase admin interface and navigate to Settings > About, or query the API endpoint /api/info/version, or inspect the installation logs for the startup version bannerAffected if The displayed version is lower than 2.10.11 (e.g., 2.10.10, 2.9.x, etc.)
-
Verify Java locale handling in authentication pathsReview application logs or proxy logs for requests containing Turkish characters (such as 'ı' or 'ſ') submitted to login, registration, or API authentication endpointsAffected if The application accepts and processes input with Turkish locale characters without normalization, and uses toUpperCase() for case conversion in security-relevant code paths
-
Inspect authentication and input validation logicExamine custom DataEase extensions or scripts that handle user input. Look for usage of toUpperCase() or toLowerCase() on username, password, or parameter values without specifying Locale.ENGLISHAffected if Custom code or extensions use locale-sensitive case conversion methods on external input without explicit locale setting
A user is affected if running DataEase version lower than 2.10.11 AND the application processes external input through Java case conversion methods in authentication or validation logic.

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 · scoped2.10.11
Upgrade DataEase to version 2.10.11 or later. No workarounds exist; immediate patching is required given the critical severity and RCE impact.
2.10.11 or later
- Back up the current Dataease installation and all associated data
- Stop the Dataease service
- Download Dataease version 2.10.11 or later from the official GitHub repository or release channel
- Follow the standard Dataease upgrade procedure for your deployment method (docker, helm, or direct installation)
- Start the Dataease service
- Verify the upgrade was successful by checking the Dataease version in the admin interface
