CVE-2026-11958

Local privilege escalation in ANSSI’s DFIR-ORC

Published Jun 18, 2026 CVSS 4.0 · 7.3 High EPSS < 1% KEV · Not listed
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.

Remediation

Vendor Solution

The vulnerability has been  fully addressed with an improved fix in 10.3.0.


Vendor Workaround

The vulnerability has been mitigated by the ANSSI team in version 10.2.8 and fully addressed with an improved fix in 10.3.0. Workaround for earlier versions: Do not execute from a too permissive directory (v10.8.0); do not run as System unless you set the temporary directory (/tempdir) to a location with appropriate permissions. (<10.2.8).
