CVE-2024-11696 1 Mozilla 2 Firefox, Thunderbird 2025-06-24 N/A N/A
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-2024-11691 2 Apple, Mozilla 17 M1, M1 Max, M1 Pro and 14 more 2025-06-24 N/A N/A
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-2023-2142 1 Mozilla 1 Nunjucks 2025-06-24 N/A N/A
In Nunjucks versions prior to version 3.2.4, it was possible to bypass the restrictions which are provided by the autoescape functionality. If there are two user-controlled parameters on the same line used in the views, it was possible to inject cross site scripting payloads using the backslash \ character.
CVE-2024-0605 1 Mozilla 1 Firefox Focus 2025-06-20 N/A 7.5 HIGH
Using a javascript: URI with a setTimeout race condition, an attacker can execute unauthorized scripts on top origin sites in urlbar. This bypasses security measures, potentially leading to arbitrary code execution or unauthorized actions within the user's loaded webpage. This vulnerability affects Focus for iOS < 122.
CVE-2024-0752 1 Mozilla 1 Firefox 2025-06-20 N/A 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-2024-0746 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-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-2024-0606 1 Mozilla 1 Firefox Focus 2025-06-20 N/A 6.1 MEDIUM
An attacker could execute unauthorized script on a legitimate site through UXSS using window.open() by opening a javascript URI leading to unauthorized actions within the user's loaded webpage. This vulnerability affects Focus for iOS < 122.
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-2025-2830 1 Mozilla 1 Thunderbird 2025-06-18 N/A N/A
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 N/A
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-2025-49709 1 Mozilla 1 Firefox 2025-06-16 N/A N/A
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 N/A N/A
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 N/A N/A
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 1 Mozilla 2 Firefox, Thunderbird 2025-06-13 N/A N/A
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-2025-3523 1 Mozilla 1 Thunderbird 2025-06-13 N/A N/A
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.
CVE-2023-5758 1 Mozilla 1 Firefox 2025-06-12 N/A 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 N/A 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 1 Mozilla 2 Firefox, Thunderbird 2025-06-11 N/A N/A
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-2025-5267 1 Mozilla 1 Firefox 2025-06-11 N/A N/A
A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
