Security SummaryAI
CVE-2025-13230 is a type confusion vulnerability in the V8 JavaScript and WebAssembly engine within Google Chrome versions prior to 142.0.7444.59. This flaw, classified under CWE-843, enables a remote attacker to potentially trigger heap corruption through a specially crafted HTML page. Chromium rates the issue as high severity, with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H), highlighting its potential for significant impact on confidentiality, integrity, and availability.
A remote attacker can exploit this vulnerability by enticing a user to visit a malicious website containing the crafted HTML page, requiring user interaction such as loading or rendering the page. No special privileges are needed, and the low attack complexity makes it accessible to attackers with basic web development skills. Successful exploitation could lead to heap corruption, potentially allowing arbitrary code execution within the browser's renderer process, compromising the victim's system.
