Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability in the Trend Micro Apex One management console could allow a remote attacker to upload malicious code and execute commands on affected installations. This vulnerability is similar in scope to CVE-2025-71210 but affects a different executable. Please note: although this vulnerability carries a technical critical CVSS rating, this was reported via responsible disclosure via a researcher through the Zero Day Initiative. The SaaS versions of the product have already been mitigated and no customer action required. For this particular vulnerability, an attacker must have access to the Trend Micro Apex One Management Console, so customers that have their console�s IP address exposed externally should consider mitigating factors such as source restrictions if not already applied.

Root cause

A user-supplied file name is joined with the allowed directory, but the result is never checked to confirm it is still inside that directory.
