CISA republished a Hitachi Energy PSIRT advisory disclosing CVE-2026-10763, affecting PROMOD V versions 1.0.10 and prior. The product relies on insecure HTTP communication instead of HTTPS because the underlying third-party Digipede server does not support HTTPS. This exposes sensitive data in transit to interception or manipulation, which could enable credential theft, session hijacking, or unauthorized access to the system.
Hitachi Energy has released version 1.0.11, which enables HTTPS support on the Digipede server, and recommends administrators follow the updated user guide for configuration steps. No public exploitation has been reported; this is a vendor-disclosed design weakness (CWE-1428) rather than an actively exploited vulnerability. CISA's standard ICS mitigations apply, including network isolation, firewalling control system networks, and avoiding direct internet exposure of these devices.
The affected product is deployed worldwide within the energy sector, per Hitachi Energy's own classification. Given the lack of known exploitation and the availability of a vendor fix, this is a routine patch advisory rather than an urgent, actively targeted threat.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
