Google patched 230 Chrome flaws, including an actively exploited V8 bug that could let attackers run arbitrary code through a crafted HTML page.

Google released a Chrome update fixing 230 security vulnerabilities, including one already exploited in the wild tracked as CVE-2026-87491 (CVSS score of 8.8). The medium-severity flaw affects V8, Google’s open source high-performance JavaScript and WebAssembly engine, Chrome’s JavaScript and WebAssembly engine.

Google rewarded the researcher with a $2,500 bounty for responsibly disclosing the vulnerability.
