A fix is available — apply it.

All versions of FactoryTalk View SE do not properly validate input of filenames within a project directory. A remote, unauthenticated attacker may be able to execute a crafted file on a remote endpoint that may result in remote code execution (RCE). Rockwell Automation recommends applying patch 1126289. Before installing this patch, the patch rollup dated 06 Apr 2020 or later MUST be applied. 1066644 – Patch Roll-up for CPR9 SRx.
