CVE-2026-6213
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 · uneditedA vulnerability in Remote Spark SparkView before build 1122 allows an attacker to bypasses the local connection check and achieve arbitrary code execution as root on the server side. Depending on implementation the vulnerability can be exploited by an unauthenticated attacker.
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 confidenceA vulnerability in Remote Spark SparkView before build 1122 allows attackers to bypass the local connection security check and execute arbitrary code as root on the server side. This authentication/authorization bypass enables unauthenticated remote code execution in certain implementations.

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 if SparkView is installedLook for SparkView process or service on the system. On Linux: 'ps aux | grep -i spark' or 'systemctl list-units | grep -i spark'. On Windows: check installed programs or running services named 'SparkView' or similar.Affected if SparkView process or service is found running on the system
-
Determine installed SparkView build versionCheck the SparkView version or build number. Common methods: (1) Query the service directly if it exposes version info, (2) Check installation directory for version files, (3) Use 'sparkview --version' or similar CLI if available, (4) Check Windows Registry or Linux package manager for installed version.Affected if Installed build version is less than 1122 (e.g., build 1121, 1120, or earlier)
-
Verify local connection security is configuredExamine SparkView configuration files for security settings related to local connections. Look for settings controlling authentication requirements for localhost/127.0.0.1 connections. Check config files in installation directory or /etc/sparkview/.Affected if Local connection security check is disabled or allows unauthenticated access
-
Check network exposure of SparkView serviceDetermine if SparkView listens on network interfaces beyond localhost. Use 'netstat -tlnp | grep -i spark' or 'ss -tlnp | grep -i spark' to see listening ports and bound addresses. If bound to 0.0.0.0 or non-localhost IP, the service is network-accessible.Affected if SparkView is listening on a network interface accessible to untrusted users (not localhost-only)
You are affected if SparkView is installed with a build version before 1122 AND the service is network-accessible or has local connection security checks disabled.

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 dataUpdate SparkView to build 1122 or later to remediate the vulnerability; if immediate patching is not feasible, implement network segmentation to restrict access to the SparkView service.
