CVE-2026-34929
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 · uneditedAn origin validation vulnerability in the Apex One/SEP agent could allow a local attacker to escalate privileges on affected installations. This is similar to CVE-2026-34927 but exists in a different inter-process communication mechanism. 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 confidenceA local privilege escalation vulnerability in Apex One/SEP agent stems from improper origin validation in an inter-process communication mechanism, allowing a low-privileged attacker to execute code with elevated privileges. This affects the security product's IPC channels used for communication between components.

Identify if Apex One or SEP agent is installedCheck for Trend Micro Apex One or Symantec Endpoint Protection (SEP) agent components in installed programs or running processes. Look for processes such as 'Apex One', 'Trend Micro', 'TmCcSvc', 'SP硝', or similar Trend Micro/SEP related services.Affected if The software is present on the system
Detection requires confirming the installed version is below 14.0.0.17079 or 14.0.20731, and that the Apex One/SEP agent service is running.

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.
dbcve · scoped14.0.0.1707914.0.20731
Apply vendor patches when available; in the interim, limit local user permissions and restrict access to the affected security agent processes and directories to reduce the attack surface.
Apex One version 14.0.0.17079 or later (or 14.0.20731 or later)
- Identify the current installed version of Apex One or SEP agent
- Download the latest version of Apex One from the official Trend Micro download center or contact Trend Micro support for the specific fixed release (14.0.0.17079 or later, or 14.0.20731 or later)
- Review release notes for any prerequisites or specific upgrade instructions
- Create a backup of the current configuration
- Stop the Apex One services before upgrading
- Apply the upgrade following Trend Micro's standard upgrade procedure
- Restart the Apex One services after upgrade
- Verify the version has been successfully updated to a fixed release
