CVE-2026-3063 is a high-severity inappropriate implementation flaw in DevTools in Google Chrome prior to 145.0.7632.116. The weakness allows a malicious browser extension, once installed by a user, to inject script or HTML into a privileged browser page through DevTools. The issue is rooted in improper handling of trust and boundary separation between extension-controlled content and privileged browser contexts exposed through developer tooling. Successful exploitation can break expected isolation guarantees around privileged pages and enable attacker-controlled content to execute or render where it should not be permitted.
