| If an attacker could find a way to trigger a particular code path in `SafeRefPtr`, it could have triggered a crash or potentially be leveraged to achieve code execution. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9. | |||||
| CVE-2024-6607 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-07-16 | N/A | 8.8 HIGH |
| It was possible to prevent a user from exiting pointerlock when pressing escape and to overlay customValidity notifications from a `<select>` element over certain permission prompts. This could be used to confuse a user into giving a site unintended permissions. This vulnerability affects Firefox < 128 and Thunderbird < 128. | |||||
| 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. | |||||
| CVE-2024-11691 | 2 Apple, Mozilla | 17 M1, M1 Max, M1 Pro and 14 more | 2025-06-24 | N/A | 8.8 HIGH |
| 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. | |||||
| CVE-2024-0751 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2025-06-20 | N/A | 8.8 HIGH |
| A malicious devtools extension could have been used to escalate privileges. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7. | |||||
| CVE-2024-0750 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2025-06-20 | N/A | 8.8 HIGH |
| A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7. | |||||
| CVE-2024-0746 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2025-06-20 | N/A | 6.5 MEDIUM |
| A Linux user opening the print preview dialog could have caused the browser to crash. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7. | |||||
| CVE-2025-2830 | 1 Mozilla | 1 Thunderbird | 2025-06-18 | N/A | 6.3 MEDIUM |
| By crafting a malformed file name for an attachment in a multipart message, an attacker can trick Thunderbird into including a directory listing of /tmp when the message is forwarded or edited as a new message. This vulnerability could allow attackers to disclose sensitive information from the victim's system. This vulnerability is not limited to Linux; similar behavior has been observed on Windows as well. This vulnerability affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2. | |||||
| CVE-2025-3522 | 1 Mozilla | 1 Thunderbird | 2025-06-18 | N/A | 6.3 MEDIUM |
| Thunderbird processes the X-Mozilla-External-Attachment-URL header to handle attachments which can be hosted externally. When an email is opened, Thunderbird accesses the specified URL to determine file size, and navigates to it when the user clicks the attachment. Because the URL is not validated or sanitized, it can reference internal resources like chrome:// or SMB share file:// links, potentially leading to hashed Windows credential leakage and opening the door to more serious security issues. This vulnerability affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2. | |||||
| CVE-2025-3523 | 1 Mozilla | 1 Thunderbird | 2025-06-13 | N/A | 6.4 MEDIUM |
| When an email contains multiple attachments with external links via the X-Mozilla-External-Attachment-URL header, only the last link is shown when hovering over any attachment. Although the correct link is used on click, the misleading hover text could trick users into downloading content from untrusted sources. This vulnerability affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2. | |||||
