Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 140. | |||||
| CVE-2025-6431 | 2 Google, Mozilla | 2 Android, Firefox | 2025-07-03 | N/A | 6.5 MEDIUM |
| When a link can be opened in an external application, Firefox for Android will, by default, prompt the user before doing so. An attacker could have bypassed this prompt, potentially exposing the user to security vulnerabilities or privacy leaks in external applications. *This bug only affects Firefox for Android. Other versions of Firefox are unaffected.* This vulnerability affects Firefox < 140. | |||||
| CVE-2023-4104 | 1 Mozilla | 1 Vpn | 2025-07-03 | N/A | 5.5 MEDIUM |

| CVE-2024-1936 | 2 Debian, Mozilla | 2 Debian Linux, Thunderbird | 2025-06-30 | N/A | 7.5 HIGH |
| The encrypted subject of an email message could be incorrectly and permanently assigned to an arbitrary other email message in Thunderbird's local cache. Consequently, when replying to the contaminated email message, the user might accidentally leak the confidential subject to a third-party. While this update fixes the bug and avoids future message contamination, it does not automatically repair existing contaminations. Users are advised to use the repair folder functionality, which is available from the context menu of email folders, which will erase incorrect subject assignments. This vulnerability affects Thunderbird < 115.8.1. | |||||
| CVE-2009-2466 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-25 | 10.0 HIGH | N/A |
| The JavaScript engine in Mozilla Firefox before 3.0.12 and Thunderbird allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) nsDOMClassInfo.cpp, (2) JS_HashTableRawLookup, and (3) MirrorWrappedNativeParent and js_LockGCThingRT. | |||||
| CVE-2024-11705 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-24 | N/A | 9.1 CRITICAL |
| `NSC_DeriveKey` inadvertently assumed that the `phKey` parameter is always non-NULL. When it was passed as NULL, a segmentation fault (SEGV) occurred, leading to crashes. This behavior conflicted with the PKCS#11 v3.0 specification, which allows `phKey` to be NULL for certain mechanisms. This vulnerability affects Firefox < 133 and Thunderbird < 133. | |||||
| CVE-2024-11698 | 2 Apple, Mozilla | 3 Macos, Firefox, Thunderbird | 2025-06-24 | N/A | 9.8 CRITICAL |
| A flaw in handling fullscreen transitions may have inadvertently caused the application to become stuck in fullscreen mode when a modal dialog was opened during the transition. This issue left users unable to exit fullscreen mode using standard actions like pressing "Esc" or accessing right-click menus, resulting in a disrupted browsing experience until the browser is restarted. *This bug only affects the application when running on macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5. | |||||

| Certain WebGL operations on Apple silicon M series devices could have lead to an out-of-bounds write and memory corruption due to a flaw in Apple's GPU driver. *This bug only affected the application on Apple M series hardware. Other platforms were unaffected.* This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Firefox ESR < 115.18, Thunderbird < 133, Thunderbird < 128.5, and Thunderbird < 115.18. | |||||
