About this tag
The browser sandbox escape tag on WindowsForum.com covers vulnerabilities that allow an attacker to break out of a browser's sandbox after first compromising the renderer process. Recent threads focus on Chrome and Chromium-based browsers like Microsoft Edge, detailing CVEs such as CVE-2026-13785, CVE-2026-14412, CVE-2026-13798, CVE-2026-14055, CVE-2026-14056, CVE-2026-14093, CVE-2026-12451, and CVE-2026-11692. These flaws often involve input validation, heap buffer overflows, use-after-free, or media handling issues that can be triggered by crafted HTML pages or video files. Discussions highlight the gap between Chromium's own severity labels and higher CVSS scores from CISA, emphasizing the importance of updating Chrome and verifying Chromium-based browsers in enterprise environments.
