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
An origin validation error vulnerability in Trend Micro Apex One could allow a local attacker to escalate privileges on affected installations. Please note: an attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

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

This is an origin validation error vulnerability in Trend Micro Apex One, a endpoint protection solution. The flaw allows a local attacker who already has low-privileged code execution to escalate to higher (likely SYSTEM) privileges by exploiting improper validation of the origin of certain operations or requests within the Apex One service.

MitigationApply the vendor-supplied patch for CVE-2025-71213 when available. Until then, minimize the attack surface by restricting local code execution privileges and monitoring for suspicious processes interacting with the Apex One service.

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. Verify Apex One agent is installed
    Check for Apex One installation by querying the Windows Registry key HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\Apex One, or look for the product in Add/Remove Programs, or inspect the installation directory typically at C:\Program Files\Trend Micro\Apex One
    Affected if Apex One is not found on the system, this CVE does not apply
  2. Retrieve installed Apex One version
    Query the registry value "Version" under HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\Apex One, or check the version information of the file SpyAgent.exe in the Apex One installation directory
    Affected if Unable to determine the version - manual inspection required
  3. Compare version against affected thresholds
    Compare the retrieved version number against the affected ranges: version < 14.0.0.14136 OR version < 14.0.20315. Note that 14.0.0.x and 14.0.2xxx are different release branches - either condition being true indicates the installed version is vulnerable
    Affected if Version falls below either 14.0.0.14136 or 14.0.20315 (whichever branch the installed version belongs to)
  4. Assess user access context
    Review local user accounts and groups on the system to determine if untrusted or low-privileged users have local account access. This vulnerability requires an attacker to first achieve low-privileged code execution
    Affected if Untrusted local users exist on the system and the Apex One version is vulnerable - the privilege escalation path becomes relevant

The system is affected by CVE-2025-71213 if the Apex One agent is installed with a version below 14.0.0.14136 or below 14.0.20315, and the environment contains low-privileged users who could potentially trigger the privilege escalation chain.

Recommended fix Moderate confidence

Apex One version 14.0.14136 or higher, or version 14.0.20315 or higher

  1. 1. Identify the current installed version of Trend Micro Apex One on the target system
  2. 2. Navigate to the Trend Micro Apex One administration console or use the product's built-in update mechanism
  3. 3. Check for available updates or patches for Apex One
  4. 4. Apply the update to upgrade to version 14.0.14136 or higher, OR version 14.0.20315 or higher (depending on your version branch)
  5. 5. Verify the installation was successful and the version has been updated
  6. 6. Restart the Apex One services if required by the update process
  7. 7. Confirm the vulnerability is remediated by checking the new version number
