What is CVE-2026-91737?
CVE-2026-91737 is a critical vulnerability found in Google Chrome, specifically within its PDF processing component. This vulnerability arises from a "use after free" flaw, which permits a remote attacker to execute arbitrary code within the browser's sandbox environment by leveraging a crafted HTML page. Google Chrome serves millions of users as one of the leading web browsers, and its PDF processing capabilities are widely used for viewing and interacting with PDF documents online. The potential exploitation of this vulnerability could severely compromise user security, allowing attackers to manipulate system resources, extract sensitive information, and jeopardize overall system integrity, especially if organizations do not implement timely updates.
