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