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 · unedited
A Server-Side Template Injection (SSTI) vulnerability in the Freemarker template engine of Datart v1.0.0-rc.3 allows authenticated attackers to execute arbitrary code via injecting crafted Freemarker template syntax into the SQL script field.

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 confidence

A Server-Side Template Injection (SSTI) vulnerability exists in the Freemarker template engine of Datart v1.0.0-rc.3. Authenticated attackers can inject malicious Freemarker template syntax into the SQL script field, leading to arbitrary code execution on the server due to unsafe template rendering.

MitigationUpgrade to a patched version of Datart that addresses this vulnerability, or implement input validation/sanitization to prevent Freemarker template syntax from being processed in the SQL script field.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Datart installation
    Locate the Datart application installation directory or check running services for the Datart web application
    Affected if Datart is installed and running
  2. Identify installed Datart version
    Check the application version file, about page, or startup logs for the exact Datart version number
    Affected if The installed version is v1.0.0-rc.3 or any version prior to the patched release
  3. Verify SQL script feature is accessible
    Check if the SQL script field functionality is enabled in the Datart configuration or admin settings
    Affected if Users with authenticated access can create or edit SQL scripts through the interface
  4. Confirm Freemarker template processing in SQL fields
    Inspect the template rendering configuration or test submitting Freemarker syntax (such as ${7*7}) into a SQL script field to see if it gets evaluated
    Affected if Freemarker template expressions are parsed and rendered rather than treated as plain text

You are affected if running Datart v1.0.0-rc.3 or earlier where authenticated users can submit SQL scripts containing Freemarker template syntax that gets processed by the template engine.

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.
