    "summary": "Following the recent Chrome sandbox escape (CVE-2025-2783), various Firefox\ndevelopers identified a similar pattern in our IPC code. A compromised child\nprocess could cause the parent process to return an unintentionally\npowerful handle, leading to a sandbox escape.\nThe original vulnerability was being exploited in the wild.\n*This only affects Firefox on Windows. Other operating systems are unaffected.*",
