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
VoidBot Open-Source is a customizable Discord bot. VoidBot Open-Source versions 0.0.1 through 0.8.1 contain a vulnerability in the command handler where permission checks are not properly enforced for certain administrative commands. This allows users without the required roles or privileges to execute sensitive commands such as `ban`, `kick`, or `shutdown`, potentially disrupting server operations. Version 1.0.0 fixes the issue.

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

VoidBot Open-Source versions 0.0.1-0.8.1 have a flaw in the command handler where permission checks are not properly enforced for administrative commands. This authorization bypass allows any user to execute sensitive commands like ban, kick, or shutdown without the required Discord roles or privileges.

MitigationUpgrade VoidBot to version 1.0.0 which contains the proper permission check enforcement. If immediate upgrade is not possible, disable or restrict access to administrative commands until the patch can be applied.

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 VoidBot version
    Locate the version file or check the bot's version using a version/info command (such as /version or !version). Common locations include package.json, version.txt, or a version embed in the bot's help info.
    Affected if The installed version is 0.0.1 through 0.8.1 (inclusive)
  2. Verify command handler is in use
    Confirm that the bot is using its native command handler to process user inputs. Check if commands like ban, kick, or shutdown are registered and accessible to users.
    Affected if The command handler module is active and processing user-submitted commands
  3. Inspect administrative command exposure
    Test or examine whether ban, kick, or shutdown commands can be invoked by users without Discord administrator or moderator roles. Attempt to execute these commands with a standard user account or review the command permission configuration.
    Affected if Administrative commands are reachable by any user regardless of Discord role status
  4. Check permission enforcement code
    Review the command handler source code or configuration files for permission validation logic. Look for role-based access control (RBAC) checks before command execution, particularly for sensitive administrative functions.
    Affected if No role or permission verification exists before administrative commands execute

A defender is affected if VoidBot version 0.0.1-0.8.1 is running and the command handler processes administrative commands (ban, kick, shutdown) without verifying the user's Discord roles or privileges.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade VoidBot to version 1.0.0 which contains the proper permission check enforcement. If immediate upgrade is not possible, disable or restrict access to administrative commands until the patch can be applied.

Recommended fix High confidence

1.0.0

  1. 1. Identify the current VoidBot version by checking the package.json or bot startup logs
  2. 2. Create a complete backup of your current VoidBot installation including configuration files and any custom code
  3. 3. Stop the running VoidBot instance
  4. 4. Update the bot to version 1.0.0 by modifying package.json version field or running the appropriate package manager update command (e.g., npm install [email protected] or git pull with version tag)
  5. 5. Review the release notes for version 1.0.0 for any required migration steps
  6. 6. Restart the VoidBot instance
  7. 7. Test that permission checks are now properly enforced by attempting to use admin commands (ban, kick, shutdown) with a non-privileged user to verify the vulnerability is fixed
Caveat Review release notes for version 1.0.0 - minor or major version changes may include breaking API or configuration changes
