browser data leak

The browser data leak tag on WindowsForum covers discussions about vulnerabilities that allow unauthorized access to cross-origin data through web browsers. A key example is CVE-2026-11685, a high-severity Chromium MediaCapture flaw affecting Google Chrome on macOS before version 149.0.7827.103, which could let remote attackers leak data via a crafted HTML page. While this specific bug targets macOS, the tag highlights broader browser security issues relevant to Windows users, including the risks of trusted browser features like camera and microphone permissions. The tag emphasizes that such leaks are often underestimated because they don't involve malware or crashes, but they undermine the same-origin boundary that protects user data.
