Logic bug in process allocation allowed to read arbitrary files
CVE-2023-23597 is fixed in 5 products on 2 platforms, first by Mozilla Firefox (en-US) 109.0, released January 17, 2023. It is not reported as exploited. Patch Radar priority: Routine.
A compromised web child process could disable web security opening restrictions, leading to a new child process being spawned within the `file://` context. Given a reliable exploit primitive, this new process could be exploited again leading to arbitrary file read. This vulnerability affects Firefox < 109.
