CVE-2025-56819
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 · uneditedAn issue in Datart v.1.0.0-rc.3 allows a remote attacker to execute arbitrary code via the INIT connection parameter.
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 · moderate confidenceDatart v1.0.0-rc.3 contains a critical code injection vulnerability in its connection initialization logic. The INIT connection parameter is not properly sanitized, allowing an attacker to inject and execute arbitrary operating system commands remotely. This RCE vulnerability requires no authentication and can be exploited by sending specially crafted connection requests.

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.
-
Confirm Datart is running in your environmentIdentify the Datart process or service running on your system. Look for processes named 'datart' or services listening on typical Datart ports (typically 8080 or as configured).Affected if Datart process or service is identified and running.
-
Check the installed Datart versionRetrieve the version of the running Datart instance. This can typically be found via the application UI (often in an 'About' or 'Version' section), API endpoint, or by inspecting the deployed binaries/container image tags. Compare your version to the affected range: version 1.0.0 (specifically v1.0.0-rc.3).Affected if The installed version is 1.0.0 or v1.0.0-rc.3.
-
Verify connection initialization feature is accessibleDetermine if the connection initialization logic is exposed in your deployment. This is typically triggered when establishing database or data source connections within the Datart application. Check if users can configure or initiate new data connections.Affected if The connection creation/initialization feature is accessible to users or API callers.
-
Assess network exposure of the Datart serviceReview network configuration to determine if the Datart service is accessible from untrusted networks. Check firewall rules, reverse proxy settings, and whether the service binds to 0.0.0.0 or a public IP address.Affected if The Datart service is reachable from untrusted network segments or the internet without strong access controls.
You are affected if Datart version 1.0.0 is running and the connection initialization feature is network-accessible, allowing remote injection of commands through the unsanitized INIT parameter.

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.
From vendor dataUpgrade to a patched version of Datart if available; otherwise, implement strict input validation and whitelisting on all connection parameters, particularly INIT, and restrict network access to the Datart service.
