CVE-2026-6958

CVE-2026-6958 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Acunetix 25.11.251107123 for Windows contains a local privilege escalation vulnerability in the Web Vulnerability Scanning Engine (wvsc.exe) that allows low-privileged local attackers to execute arbitrary code as SYSTEM by exploiting a missing hardcoded directory path for OpenSSL-related files. Attackers can create the missing directory, place a malicious file at the expected path, and cause the SYSTEM-level wvsc.exe process to load and execute it, resulting in full privilege escalation.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
