Local privilege escalation in Trend Micro Apex One and Apex One as a Service agents allows an attacker with low-privileged code execution to win a race condition in the endpoint protection agent and elevate to higher privileges. The flaw is a time-of-check time-of-use (TOCTOU) weakness (CWE-367) in the Apex One/SEP agent on Windows endpoints, with no public exploit identified at time of analysis and not currently listed in CISA KEV. The vendor has published advisory KA-0023430 with fixed builds.
Local privilege escalation in Trend Micro Apex One and Apex One as a Service allows an authenticated low-privileged user to elevate to higher privileges by abusing an origin validation flaw in one of the agent's process protection communication mechanisms. No public exploit identified at time of analysis, but the vulnerability is companion to CVE-2026-45206 in a parallel code path, which suggests the underlying class of issue is actively being researched by Trend Micro's own team.
Local privilege escalation in Trend Micro Apex One and Apex One as a Service allows low-privileged attackers to elevate to higher privileges by abusing an origin validation weakness (CWE-346) in one of the agent's process protection communication mechanisms. The flaw is a sibling issue to CVE-2026-45207 affecting a different IPC channel and is reported by Trend Micro itself; no public exploit identified at time of analysis and the CVE is not on CISA KEV.
Local privilege escalation in Trend Micro Apex One and Apex One as a Service stems from an origin validation weakness (CWE-346) in one of the agent's process protection mechanisms, allowing a low-privileged local attacker to elevate to SYSTEM-level privileges on affected installations. The flaw was reported by Trend Micro itself and is a sibling issue to CVE-2026-34927, which affects a different process protection mechanism in the same agent. No public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Local privilege escalation in Trend Micro Apex One and Apex One as a Service agents allows an attacker with low-privileged code execution to gain elevated rights by exploiting weak origin validation in an inter-process communication channel. No public exploit identified at time of analysis, but the flaw is a sibling to CVE-2026-34927 (different IPC mechanism in the same agent) which raises the likelihood of researcher and adversary interest. Vendor patches are available for both the on-prem 2019 (14.0) line and the SaaS offering.
Local privilege escalation in Trend Micro Apex One and Apex One as a Service security agents allows a low-privileged attacker who already has code execution on the endpoint to elevate to higher privileges by abusing a named pipe that fails to validate the origin of incoming connections. The flaw is companion to CVE-2026-34927 (a sibling issue in a different named pipe) and currently has no public exploit identified at time of analysis, but its presence in widely-deployed endpoint security software materially raises post-compromise risk.
Local privilege escalation in Trend Micro Apex One (on-premises 2019/14.0) and Apex One as a Service allows a low-privileged user already executing code on the host to elevate to higher privileges by abusing an origin validation weakness in the security agent. The flaw carries a CVSS 7.8 (local, low complexity) and no public exploit identified at time of analysis, but because the agent typically runs with SYSTEM-level rights, successful exploitation yields full host compromise. Trend Micro has issued patched builds (KA-0023430).
Directory traversal in Trend Micro Apex One on-premise server (versions before 14.0.0.17079) enables a highly privileged local attacker to manipulate a key server table and inject malicious code that propagates to all managed endpoint agents, effectively weaponizing the EDR platform's own distribution infrastructure. The attack requires an adversary who has already obtained administrative credentials to the Apex One server through a separate compromise vector. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the changed scope (S:C) in the CVSS vector signals that a successful exploit extends impact beyond the server itself to the entire managed agent fleet.
Local privilege escalation in the Trend Micro Apex One (Mac) agent lets a low-privileged user abuse a flaw in the agent's self-protection mechanism to gain elevated (root-level) control on affected macOS installations. The root cause is an origin validation error (CWE-346) in the component meant to prevent tampering with the security agent itself. There is no public exploit identified at time of analysis; EPSS is negligible (0.01%) and CISA SSVC records no known exploitation, but a Zero Day Initiative advisory (ZDI-26-143) confirms independent researcher validation of the issue.
Local privilege escalation in the Trend Micro Apex One (mac) endpoint agent lets a low-privileged user who already has code execution on a macOS host abuse a race condition in the agent's cache mechanism to gain full (root-level) control. The flaw was reported by Trend Micro/ZDI (ZDI-26-142) and carries a CVSS of 7.8; there is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and CISA SSVC records exploitation status as none.
Local privilege escalation in the Trend Micro Apex One (mac) agent stems from a race condition in the iCore service's signature verification routine, letting a low-privileged local attacker on affected macOS installations swap a verified file after the check but before use to run code with elevated (root-level) privileges. There is no public exploit identified at time of analysis, and SSVC/EPSS signals both indicate exploitation has not been observed; Trend Micro credited its own team with the report and states the issue was already remediated through ActiveUpdate/SaaS releases in mid-to-late 2025.
Local privilege escalation in the Trend Micro Apex One (mac) agent lets an attacker who already runs low-privileged code abuse an origin validation weakness (CWE-346) in the iCore service to gain full control of the endpoint. The flaw yields total confidentiality, integrity, and availability impact (CVSS 7.8) but requires an existing foothold, and no public exploit identified at time of analysis. It was discovered through the Zero Day Initiative (ZDI-26-139) and reported by the vendor; EPSS is negligible at 0.01% and CISA SSVC records no observed exploitation.
Local privilege escalation in Trend Micro Apex One and Apex One as a Service stems from an origin validation error (CWE-346) that lets an authenticated low-privileged attacker elevate to higher privileges on the host. Trend Micro has released fixed builds and ZDI has published an advisory (ZDI-26-140); no public exploit identified at time of analysis, though vendor-reported vulnerabilities in endpoint security agents are frequent targets for post-compromise attackers.
Local privilege escalation in the Trend Micro Apex One scan engine allows low-privileged users on Windows endpoints to gain elevated privileges by abusing a link-following weakness (CWE-59) in the scanner's file-handling logic. The flaw affects on-premise Apex One 2019 builds prior to 14.0.0.14136 and the SaaS edition prior to 14.0.20315, with a patch available from Trend Micro; no public exploit identified at time of analysis, and the issue is not currently listed in CISA KEV.
Remote code execution in the Trend Micro Apex One management console allows attackers with console access to upload malicious files via a path traversal flaw (CWE-22) and execute arbitrary commands on the server. The on-premises product (versions before 14.0.0.14136) is affected, while SaaS deployments have already been remediated by the vendor. No public exploit identified at time of analysis; the issue was responsibly disclosed through the Zero Day Initiative (ZDI-26-137).

The on-premises Apex One 2019 (14.0) prior to 14.0.0.14136 is impacted, while the SaaS variant (below 14.0.20315) has already been mitigated by the vendor; no public exploit identified at time of analysis, though it was reported through the Zero Day Initiative.
