When Firefox is configured to block storage of all cookies, it was still possible to store data in localstorage by using an iframe with a source of ‘about:blank’. This could have led to malicious websites storing tracking data without permission.
An attacker could have triggered a use-after-free condition when creating a WebRTC connection over HTTPS.
Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to be stored in the main compartment resulting in a use-after-free.
Insufficient validation in the Drag and Drop API in conjunction with social engineering, may have allowed an attacker to trick end-users into creating a shortcut to local system files. This could have been leveraged to execute arbitrary code.
A website could have obscured the fullscreen notification by using an option element by introducing lag via an expensive computational function. This could have led to user confusion and possible spoofing attacks.
The use of RTL Arabic characters in the address bar may have allowed for URL spoofing.
Uploading files which contain symlinks may have allowed an attacker to trick a user into submitting sensitive data to a malicious website.
A website could have obscured the fullscreen notification by using a URL with a scheme handled by an external program, such as a mailto URL. This could have led to user confusion and possible spoofing attacks.
When opening Diagcab files, Firefox did not warn the user that these files may contain malicious code.
A use-after-free condition existed in NotifyOnHistoryReload where a LoadingSessionHistoryEntry object was freed and a reference to that object remained. This resulted in a potentially exploitable condition when the reference to that object was later reused.
A website could prevent a user from exiting full-screen mode via alert and prompt calls. This could lead to user confusion and possible spoofing attacks.
Memory safety bugs present in Firefox 114, Firefox ESR 102.12, and Thunderbird 102.12. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
