What is CVE-2026-6958?

A local privilege escalation vulnerability exists in Acunetix 25.11.251107123 due to the missing hardcoded directory path for OpenSSL-related files in the Web Vulnerability Scanning Engine (wvsc.exe). Low-privileged local attackers can exploit this flaw by creating the missing directory and placing a malicious executable at the expected path. When the SYSTEM-level wvsc.exe process loads this file, it allows attackers to execute arbitrary code with elevated privileges, leading to potential system compromise.
