Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2023-37201, CVE-2023-37202, CVE-2023-37205, CVE-2023-37207, CVE-2023-37209, CVE-2023-37210, CVE-2023-37211, CVE-2023-37212) Martin Hostettler discovered that Firefox did not properly block storage of all cookies when configured.
