About this tag
The cross-origin data leak tag on WindowsForum covers Chromium vulnerabilities that allow an attacker who has already compromised the renderer process to leak data from another origin through a crafted HTML page. These flaws are typically rated medium or low severity but are significant because they break the browser's origin isolation promise. Topics include CVE-2026-11691 (Chrome New Tab Page), CVE-2026-11007 (WebView), CVE-2026-11145 (geolocation race), CVE-2026-7942 (ANGLE integer overflow), CVE-2026-8011 (Search policy enforcement), and CVE-2025-5064 (Background Fetch API). For Windows users and administrators, these vulnerabilities highlight the importance of prompt patching and treating Chromium security as part of the operating environment.
