Security researchers have discovered that Chromium-based browsers, including Google Chrome, Microsoft Edge, Vivaldi, Brave, and Opera, contain 31 high-risk security vulnerabilities (CVE-2026-3909, CVE-2026-3910, CVE-2026-3913 to CVE-2026-3932, and CVE-2026-3934 to CVE-2026-3942). The vulnerability types include Out-of-bounds Write, Code Injection, and Use After Free. In the worst-case scenario, an unauthenticated remote attacker could exploit these vulnerabilities via specially crafted HTML pages to execute arbitrary code within the browser sandbox environment. Among them, CVE-2026-3909 and CVE-2026-3910 have already been exploited by attackers. Please verify your systems and apply the necessary patches as soon as possible.
