After downloading a Windows <code>.url</code> shortcut from the local filesystem, an attacker could supply a remote path that would lead to unexpected network requests from the operating system. This also had the potential to leak NTLM credentials to the resource.<br>*This bug only affects Firefox on Windows. Other operating systems are unaffected.*.

An attacker could have caused an out of bounds memory access using WebGL APIs, leading to memory corruption and a potentially exploitable crash. *This bug only affects Firefox and Thunderbird for macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 112, Firefox ESR < 102.10, and Thunderbird < 102.10.
CVE-2023-23599 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-10-24 N/A 6.5 MEDIUM

Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash.

CVE-2023-34414 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-10-24 N/A 3.1 LOW
The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed. With the right timing the elicited clicks could land in that gap and activate the button that overrides the certificate error for that site. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12.
CVE-2023-4045 2 Debian, Mozilla 2 Debian Linux, Firefox 2026-10-24 N/A 5.3 MEDIUM

CVE-2023-0767 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-10-24 N/A 8.8 HIGH

CVE-2023-23605 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-10-24 N/A 8.8 HIGH
Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and Firefox ESR 102.6.
