Siemens has disclosed CVE-2026-67367, a directory traversal vulnerability (CWE-23) affecting the embedded HTTP server's file-serving endpoint in SIMOVE Fleetmanager and SIPLANT products. The flaw stems from improper validation of directory traversal sequences, allowing an unauthenticated remote attacker to read arbitrary files from the underlying operating system without any credentials. This could expose sensitive data such as credential stores, private keys, and configuration secrets.
Affected products span multiple version lines: SIMOVE Fleetmanager V3.1 (<3.1.13), V3.2 (<3.2.4), V3.3 (<3.3.2), V4.0 (<4.0.1), and SIPLANT V1.7, V2.2, V3.0 (all versions), and V3.1 (<3.1.4). Siemens has released fixed versions for most affected lines; SIPLANT V1.7, V2.2, and V3.0 have no vendor fix and require contacting Siemens customer support directly. There is no indication of active exploitation in the wild; this is a vendor-disclosed advisory republished by CISA.
Defenders operating these products in industrial/manufacturing environments should prioritize updating to the fixed versions where available, restrict network access to the affected HTTP servers, and follow standard ICS network segmentation practices (isolating control system networks behind firewalls, avoiding direct internet exposure, and using VPNs for remote access). Given the unauthenticated nature of the flaw and potential for credential/secret exposure, organizations should treat exposed instances as a priority for remediation even absent confirmed in-the-wild exploitation.

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 its extracted indicators and 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 16,445 reports from 149 sources, 666 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.
