What is CVE-2026-11958?
CVE-2026-11958 is a high-severity vulnerability in ANSSI DFIR-ORC, published on 18 Jun 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Local privilege escalation by loading DLLs from a shared temporary directory in ANSSI’s DFIR-ORC, versions 10.2.7 and prior. An attacker with prior access to the system, can place a malicious DLL in C:\Windows\Temp and wait for the application to be executed. Because DFIR-ORC is extracted and executed from that location with administrative privileges, the malicious library can be loaded automatically, allowing the attacker to gain administrator privileges on the affected machine.
