potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2023-4047,
CVE-2023-4048, CVE-2023-4049, CVE-2023-4051, CVE-2023-4053, CVE-2023-4055,
CVE-2023-4056, CVE-2023-4057, CVE-2023-4058)

access image data from another site in violation of same-origin policy.
(CVE-2023-4045)
Alexander Guryanov discovered that Firefox did not properly update the
value of a global variable in WASM JIT analysis in some circumstances. An
