A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as: Securitypolicyviolation events could have leaked cross-origin information for frame-ancestors violations.

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, trick a user into accepting unwanted permissions, conduct header splitting attacks, conduct spoofing attacks, bypass security restrictions, confuse the user, or execute arbitrary code.
