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.","published":"2026-09-04T15:17:35.360","modified":"2026-09-04T15:17:35.360","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://olografix.org/acme/_poc/CVE-2026-6958.pdf"},{"type":"WEB","url":"https://seclists.org/fulldisclosure/2026/Sep/0"},{"type":"WEB","url":"https://www.acunetix.com/"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/acunetix-local-privilege-escalation-via-wvsc-exe"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-04T15:17:35.360"}}
