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. An attacker could potentially exploits this
issue to store tracking data without permission in localstorage.
( CVE-2023-3482 )
Paul Nickerson discovered that Firefox did have insufficient validation in
the Drag and Drop API. If a user were tricked into creating a shortcut to
local system files, an attacker could execute arbitrary code.
( CVE-2023-37203 )
