Three critical vulnerabilities have been reported by Siemens in the SIMATIC Drive Controller CPU 1504D TF. Each received a 9.6 rating from the vendor. The problems enable execution of JavaScript in a browser after tricking a user into importing a malicious trace file, potentially leading to PLC operations.

An attacker needs to deceive a user with the “Read diagnostics” right into loading a malicious trace file.
Once successful, the attacker can run JavaScript they control inside the browser and carry out PLC actions via the web server, limited to the user's permissions.

A critical flaw (CVE-2026-108971, CVSS 9.6) in the D-Link DCS-930L camera on firmware B1.08B4 lets remote attackers bypass firmware signature checks. An exploit is public, and the end-of-life camera will not get a patch.
IBM disclosed CVE-2026-96012, a privilege escalation flaw in Db2 Mirror for i versions 7.4, 7.5, and 7.6 that IBM rates 9.9 CVSS. An authenticated attacker could bypass checks to execute malicious code and gain elevated privileges. Fixes are available.
CVE-2026-108693 lets an attacker run code on Windows by planting a fake gswin64c.exe that ImageMagick launches by bare name when Ghostscript is unregistered. VulnCheck, the CNA, rates it 7.0 (CVSS 3.1); NVD has not scored it yet. No fixed version is named.
The WPO365 WordPress plugin has patched two high-severity vulnerabilities in versions through 44.1. Both flaws could allow unauthenticated attackers to achieve site takeover or persistent script injection.
Winsiderss System Informer versions through 4.0.26241.138 contain an incorrect authorization flaw that lets local attackers execute code as SYSTEM from any signed process. Vulncheck rates the issue 7.8 and 8.5.
