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-2023-5724, CVE-2023-5728,
CVE-2023-5730, CVE-2023-5732)

Kelsey Gilbert discovered that Thunderbird did not properly manage certain
browser prompts and dialogs due to an insufficient activation-delay. An
attacker could potentially exploit this issue to perform clickjacking.
(CVE-2023-5721)

Shaheen Fazim discovered that Thunderbird did not properly validate the URLs
open by installed WebExtension. An attacker could potentially exploit this
issue to obtain sensitive information. (CVE-2023-5725)
