CVE-2025-64729

Victim-identity code execution via writable project files

Published Jan 16, 2026 · Updated Jan 16, 2026

Missing authorization in AVEVA Process Optimization 2024.1 and earlier allows local users to execute code as an interacting victim. Installation and data-folder ACLs fail to restrict OS Standard Users from altering project files and embedding code for later execution. Exploitation requires local low-privileged access and victim interaction, after which the embedded code runs with the victim's privileges.
