| CVE-2009-2466 | 2 Mozilla, Redhat | 3 Firefox, Thunderbird, Enterprise Linux | 2025-06-25 | 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-2025-1936 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-06-24 | 7.3 High |
| jar: URLs retrieve local file content packaged in a ZIP archive. The null and everything after it was ignored when retrieving the content from the archive, but the fake extension after the null was used to determine the type of content. This could have been used to hide code in a web extension disguised as something else like an image. This vulnerability affects Firefox < 136, Firefox ESR < 128.8, Thunderbird < 136, and Thunderbird < 128.8. | ||||
| CVE-2024-11705 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-24 | 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 | 4 Macos, Firefox, Firefox Esr and 1 more | 2025-06-24 | 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-2024-11696 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-06-24 | 5.4 Medium |
| The application failed to account for exceptions thrown by the `loadManifestFromFile` method during add-on signature verification. This flaw, triggered by an invalid or unsupported extension manifest, could have caused runtime errors that disrupted the signature validation process. As a result, the enforcement of signature validation for unrelated add-ons may have been bypassed. Signature validation in this context is used to ensure that third-party applications on the user's computer have not tampered with the user's extensions, limiting the impact of this issue. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5. | ||||
| CVE-2024-11694 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-06-24 | 6.1 Medium |
| Enhanced Tracking Protection's Strict mode may have inadvertently allowed a CSP `frame-src` bypass and DOM-based XSS through the Google SafeFrame shim in the Web Compatibility extension. This issue could have exposed users to malicious frames masquerading as legitimate content. This vulnerability affects Firefox < 133, Firefox ESR < 128.5, Firefox ESR < 115.18, Thunderbird < 133, Thunderbird < 128.5, and Thunderbird < 115.18. | ||||
| CVE-2024-11691 | 2 Apple, Mozilla | 18 M1, M1 Max, M1 Pro and 15 more | 2025-06-24 | 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-2024-0752 | 1 Mozilla | 1 Firefox | 2025-06-20 | 6.5 Medium |
| A use-after-free crash could have occurred on macOS if a Firefox update were being applied on a very busy system. This could have resulted in an exploitable crash. This vulnerability affects Firefox < 122. | ||||
| CVE-2024-0751 | 3 Debian, Mozilla, Redhat | 9 Debian Linux, Firefox, Firefox Esr and 6 more | 2025-06-20 | 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 | 3 Debian, Mozilla, Redhat | 9 Debian Linux, Firefox, Firefox Esr and 6 more | 2025-06-20 | 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 | 3 Debian, Mozilla, Redhat | 9 Debian Linux, Firefox, Firefox Esr and 6 more | 2025-06-20 | 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-2023-5496 | 2 Mozilla, Translator Poqdev Add-on Project | 2 Firefox, Translator Poqdev Add-on | 2025-06-16 | 3.1 Low |
| A vulnerability was found in Translator PoqDev Add-On 1.0.11 on Firefox. It has been rated as problematic. This issue affects some unknown processing of the component Select Text Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The identifier VDB-241649 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way. | ||||
| CVE-2025-49709 | 1 Mozilla | 1 Firefox | 2025-06-16 | 9.8 Critical |
| Certain canvas operations could have lead to memory corruption. This vulnerability affects Firefox < 139.0.4. | ||||
| CVE-2025-49710 | 1 Mozilla | 1 Firefox | 2025-06-16 | 9.8 Critical |
| An integer overflow was present in `OrderedHashTable` used by the JavaScript engine This vulnerability affects Firefox < 139.0.4. | ||||
| CVE-2025-5020 | 1 Mozilla | 1 Firefox | 2025-06-13 | 4.3 Medium |
| Opening maliciously-crafted URLs in Firefox from other apps such as Safari could have allowed attackers to spoof website addresses if the URLs utilized non-HTTP schemes used internally by the Firefox iOS client This vulnerability affects Firefox for iOS < 139. | ||||
| CVE-2025-2817 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-06-13 | 8.8 High |
| Thunderbird's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Firefox ESR < 115.23, Thunderbird < 138, and Thunderbird < 128.10. | ||||
| CVE-2023-5758 | 1 Mozilla | 1 Firefox | 2025-06-12 | 6.1 Medium |
| When opening a page in reader mode, the redirect URL could have caused attacker-controlled script to execute in a reflected Cross-Site Scripting (XSS) attack. This vulnerability affects Firefox for iOS < 119. | ||||
| CVE-2024-0748 | 1 Mozilla | 1 Firefox | 2025-06-11 | 4.3 Medium |
| A compromised content process could have updated the document URI. This could have allowed an attacker to set an arbitrary URI in the address bar or history. This vulnerability affects Firefox < 122. | ||||
| CVE-2025-5268 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2025-06-11 | 6.5 Medium |
| Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10. 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. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | ||||
| CVE-2025-5272 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-06-11 | 7.3 High |
