The point i o tag covers a reported security issue affecting Rockwell Automation’s 1734-OB8 eight-point digital output module in the POINT I/O family. The vulnerability, identified as CVE-2026-10573, involves specially crafted Common Industrial Protocol messages sent over EtherNet/IP. An affected module can be forced into a faulted state, potentially interrupting industrial processes such as conveyors and automated sequences.
