An unauthenticated remote attacker can exploit it by getting a victim to load a crafted HTML page, which allows arbitrary code execution inside the browser sandbox, and this requires user interaction (the victim visiting the page) and no special network position or configuration.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-23T07:10:33Z"},"cvss":{"score":8.8,"severity":"HIGH","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.3564,"percentile":0.98453,"date":"2026-10-28","provenance":"source"},"kev":{"dateAdded":"2022-06-08","dueDate":"2022-06-22","ransomware":false,"requiredAction":"Apply
