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
Minion event bus authorization bypass. An attacker with access to a minion key can craft a message which may be able to execute a job on other minions (>= 3007.0).

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

This is a SaltStack authorization bypass where an attacker with access to a compromised minion key can craft malicious messages through the minion event bus to execute jobs on other minions. The vulnerability exists in Salt versions >= 3007.0, allowing lateral movement within the Salt infrastructure by bypassing authorization checks on inter-minion communication.

MitigationUpgrade Salt to the patched version or implement additional event bus authorization controls. Additionally, rotate any potentially compromised minion keys and review minion key access controls to limit exposure.

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. Determine installed Salt version
    Run 'salt --version' or 'salt-minion --version' on the Salt master and minion hosts
    Affected if The version reported is 3007.0 or higher (any 3007.x, 3008.x, or later release)
  2. Verify inter-minion communication is enabled
    Inspect the Salt master configuration file (typically /etc/salt/master) for settings that allow minion-to-minion communication, such as 'minion_pub' or similar event bus publication settings
    Affected if Inter-minion communication or event bus publishing is explicitly enabled in the master configuration
  3. Confirm event bus is active
    Check if the Salt master process is running and the event bus (event publisher) is active by reviewing running processes or master logs
    Affected if The Salt master event bus is operational and accepting events from minions
  4. Review minion key acceptance policy
    Examine the Salt master configuration for 'auto_accept' settings or review the list of accepted minion keys in /etc/salt/pki/master/minions/
    Affected if Multiple minion keys are accepted or auto-accept is enabled, increasing the attack surface for lateral movement

You are affected if your Salt version is 3007.0 or higher AND inter-minion event bus communication is enabled, allowing a compromised minion key to inject malicious messages for lateral movement.

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.

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

Upgrade Salt to the patched version or implement additional event bus authorization controls. Additionally, rotate any potentially compromised minion keys and review minion key access controls to limit exposure.

Recommended fix Moderate confidence

Upgrade to the latest Salt release that includes the fix for CVE-2025-22236 (check docs.saltproject.io for the specific fixed version number)

  1. 1. Identify the currently installed Salt version using: salt --version or salt-minion --version
  2. 2. If running version 3007.0 or later, plan an upgrade to the fixed release
  3. 3. Update Salt Master and all Minions to the same fixed version to maintain compatibility
  4. 4. Test the upgrade in a non-production environment first
  5. 5. After upgrading, verify the fix by confirming that minions without proper authorization can no longer execute jobs on other minions
Caveat Ensure all minions are upgraded together to maintain consistent behavior across the fleet
