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
A vulnerability in how Palo Alto Networks PAN-OS software processes data received from Cloud Identity Engine (CIE) agents enables modification of User-ID groups. This impacts user access to network resources where users may be inappropriately denied or allowed access to resources based on your existing Security Policy rules.

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 confidence

A vulnerability in PAN-OS allows modification of User-ID groups through malicious data processed from Cloud Identity Engine (CIE) agents. This enables attackers to manipulate group mappings and bypass Security Policy rules, resulting in inappropriate denial or allowance of network resource access.

MitigationApply the vendor-supplied PAN-OS patch addressing this vulnerability and verify User-ID group mappings remain correct post-update.

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. Check PAN-OS version
    Access the firewall CLI and run 'show system info' or check via the web interface under Device > Setup > Operations > Device Information. Look for the 'PanOS' version field.
    Affected if The installed version is 10.1.0-10.1.10, 10.2.0-10.2.4, or 11.0.0-11.0.2 (i.e., it falls within the affected ranges but is before the fixed versions).
  2. Verify User-ID is enabled
    In the PAN-OS web interface, go to Device > User Identification > User-ID Settings, or run 'show user-id-bleeping' in CLI. Check if User-ID is enabled.
    Affected if User-ID is enabled and the PAN-OS version is in the affected range.
  3. Confirm Cloud Identity Engine (CIE) integration
    Check if CIE agents are configured: in the web interface, go to Device > Cloud Identity Engine > Agents, or run 'show cloud-identity-engine agents' in CLI. Also check Device > User Identification > Cloud Identity Engine Service settings.
    Affected if CIE agents are connected and syncing identity data to the firewall.
  4. Review User-ID group mappings for anomalies
    In the web interface, go to Device > User Identification > User-ID Groups. Alternatively, run 'show user group list' and compare current group mappings against known-good baselines. Look for unexpected group assignments, duplicate entries, or groups with incorrect member lists.
    Affected if Group mappings show unauthorized or unexpected modifications that do not align with your directory configuration.

You are affected if your PAN-OS version falls within the affected ranges (10.1.x before 10.1.11, 10.2.x before 10.2.5, or 11.0.x before 11.0.3), User-ID is enabled with CIE integration, and User-ID group mappings contain unexpected or unauthorized changes.

Upgrade available Upgrade to 10.1.11 / 10.2.5 / 11.0.3 or later
Fixed in 10.1.1110.2.511.0.3
Interim mitigation

Apply the vendor-supplied PAN-OS patch addressing this vulnerability and verify User-ID group mappings remain correct post-update.

Recommended fix High confidence

Upgrade to PAN-OS 10.1.11 (for 10.1.x branch), 10.2.5 (for 10.2.x branch), or 11.0.3 (for 11.0.x branch)

  1. 1. Identify the current PAN-OS version by navigating to Device > Support or using 'show system info' in the CLI
  2. 2. Determine which version branch you are running (10.1.x, 10.2.x, or 11.0.x)
  3. 3. Download the appropriate fixed release from the Palo Alto Networks Support Portal: 10.1.11 for 10.1.x branch, 10.2.5 for 10.2.x branch, or 11.0.3 for 11.0.x branch
  4. 4. Upload the update to the PAN-OS device via Device > Software > Upload, or via CLI using 'request system software upload'
  5. 5. Install the update via Device > Software > Install, or via CLI using 'request system software install <filename>'
  6. 6. After installation, reboot the device to complete the update
  7. 7. Verify the new version is installed and the vulnerability is resolved by checking Device > Support or running 'show system info'
