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
Dispatch's notification service uses Jinja templates to generate messages to users. Jinja permits code execution within blocks, which were neither properly sanitized nor sandboxed. This vulnerability enables users to construct command line scripts in their custom message templates, which are then executed whenever these notifications are rendered and sent out.

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

Jinja template injection in Dispatch's notification service allows authenticated users to inject and execute arbitrary code via custom message templates. Since Jinja templates permit code execution within blocks without sanitization or sandboxing, attackers can achieve remote code execution when notifications are rendered.

MitigationImplement proper Jinja sandboxing, disable code execution features in templates, or migrate to a safe templating engine that restricts template logic to rendering only.

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. Identify Dispatch installation
    Locate the Dispatch application in your environment and confirm its presence. Search for files named 'dispatch' or directories containing dispatch configuration.
    Affected if Dispatch software is present in the environment
  2. Determine Dispatch version
    Run 'dispatch --version' or check the installed package version via your package manager (pip, npm, etc.) Compare this version number to any official Dispatch release notes or changelogs for the version that addresses template injection.
    Affected if The installed version is unpatched and lacks Jinja sandboxing in notification templates
  3. Verify notification service is configured
    Check Dispatch configuration files (typically in a config/ or settings/ directory) for any notification-related settings. Look for entries containing 'notification', 'template', 'message', or 'alert'.
    Affected if Notification service is enabled and accepts custom template configuration
  4. Inspect template configuration for sandboxing
    Examine the notification template configuration files. Search for any 'jinja', 'sandbox', 'autoescape', or 'safe' settings. Check whether templates are stored in a templates/ directory accessible by the notification service.
    Affected if Templates are processed by Jinja without sandbox mode enabled or without disabling executable features
  5. Test template rendering capability
    If you have access, review how custom message templates are submitted to the notification system. Check whether user input flows directly into Jinja render calls without sanitization.
    Affected if Custom templates can be provided as input and are rendered without code execution restrictions

You are affected if Dispatch with an unpatched version is running and the notification service allows custom Jinja templates without sandboxing enabled.
