High CVSS 8.4

CVE-2026-0487

NVD analysis in progress

SAProuter on Microsoft Windows allows an unauthenticated attacker to load library (DLL) files from an untrusted location, allowing them to execute malicious code on the system. This could enable the attacker to hijack the DLL loading process and achieve arbitrary code execution. This has high impact on confidentiality, integrity and availability of the system.

What this means

Exposure
Exploitable with local access to the machine, without authentication and with no action from the victim.
Impact
An attacker can read sensitive data, modify or destroy data and take the service offline.
Likelihood
Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.

What to doFold into the next patch cycle.
