canvas same origin

The canvas same origin tag covers discussions about the browser same-origin policy as it applies to the HTML Canvas API, particularly security vulnerabilities that allow bypassing this policy. A key example is CVE-2026-7977, a medium-severity Chrome Canvas flaw fixed in Chrome 148 that allowed a crafted HTML page to bypass same-origin restrictions. For Windows administrators, such vulnerabilities highlight how Chromium's security boundaries affect the operating environment, even though Chrome is not part of Windows itself. The tag focuses on the intersection of web graphics, privacy boundaries, and browser security, with implications for enterprise IT managing Chromium-based browsers on Windows systems.
