CVE-2026-23958
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 analysis tool. Prior to version 2.10.19, DataEase uses the MD5 hash of the user’s password as the JWT signing secret. This deterministic secret derivation allows an attacker to brute-force the admin’s password by exploiting unmonitored API endpoints that verify JWT tokens. The vulnerability has been fixed in v2.10.19. 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 before 2.10.19 use MD5(password) as the JWT signing secret, making the secret deterministic and derivable from the password. Attackers can brute-force the admin password by using JWT verification endpoints, achieving full account compromise.

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 Dataease installed versionLocate the Dataease installation and identify its version number. This is typically found in the application interface under 'About' or 'System Information', or by checking the installation manifest or Docker image tag if deployed as a container.Affected if The installed version is any version lower than 2.10.19
-
Confirm version is below vulnerable thresholdCompare the identified version against the affected range: versions before 2.10.19. If you have a version number like 2.10.0 through 2.10.18, these are all vulnerable.Affected if The version number is less than 2.10.19 (for example, 2.10.18, 2.10.10, 2.9.5, etc.)
-
Verify JWT authentication is in useCheck if the Dataease deployment is configured to use JWT-based authentication. This is typically the default authentication method. Inspect the authentication configuration or attempt to observe JWT tokens in use.Affected if JWT authentication is enabled and users are authenticating via JWT tokens
You are affected if your Dataease version is any release prior to 2.10.19 and you are using JWT-based authentication, which is the default configuration.
Generated from the published advisory. Verify against your own configuration.
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 · scoped2.10.19
Upgrade to Dataease v2.10.19 immediately. Consider rotating all user passwords and invalidating existing JWT sessions as a precaution given the ease of exploitation.
2.10.19
- Backup all Dataease data and configurations before proceeding with the upgrade
- Stop the Dataease service
- Upgrade Dataease to version 2.10.19 or later
- Verify the upgrade was successful by checking the version number
- Restart the Dataease service
- Monitor logs for any authentication or JWT-related errors
