| CVE-2023-4052 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-10-23 | N/A | 6.5 MEDIUM |
| The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1. | |||||
| CVE-2023-23598 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-10-23 | N/A | 6.5 MEDIUM |
| Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to `DataTransfer.setData`.

| CVE-2024-8384 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-06-17 | N/A | 9.8 CRITICAL |
| The JavaScript garbage collector could mis-color cross-compartment objects if OOM conditions were detected at the right point between two passes. This could have led to memory corruption. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, Firefox ESR < 115.15, Thunderbird < 128.2, and Thunderbird < 115.15. | |||||
| CVE-2024-8383 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-06-17 | N/A | 7.5 HIGH |
| Firefox normally asks for confirmation before asking the operating system to find an application to handle a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an unscrupulous program that the user downloaded could register itself as a handler. The website that served the application download could then launch that application at will. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, and Firefox ESR < 115.15. | |||||
| CVE-2024-8382 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-06-17 | N/A | 8.8 HIGH |
| Internal browser event interfaces were exposed to web content when privileged EventHandler listener callbacks ran for those events. Web content that tried to use those interfaces would not be able to use them with elevated privileges, but their presence would indicate certain browser features had been used, such as when a user opened the Dev Tools console. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, Firefox ESR < 115.15, Thunderbird < 128.2, and Thunderbird < 115.15. | |||||
