Details

Multiple security issues were discovered in Thunderbird. If a user were
tricked into opening a specially crafted website in a browsing context, an
attacker could potentially exploit these to cause a denial of service,
obtain sensitive information, bypass security restrictions, cross-site
tracing, or execute arbitrary code. (CVE-2023-32205, CVE-2023-32207,
CVE-2023-32211, CVE-2023-32212, CVE-2023-32213, CVE-2023-32215)
