| CVE-2024-8383 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Enterprise Linux and 5 more | 2025-11-04 | 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 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-04 | 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. | ||||

| CVE-2024-9401 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-03 | 9.8 Critical |
| Memory safety bugs present in Firefox 130, Firefox ESR 115.15, Firefox ESR 128.2, and Thunderbird 128.2. 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.

| CVE-2024-9394 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-03 | 6.1 Medium |
| An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the `resource://devtools` origin. This could allow them to access cross-origin JSON content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Firefox ESR < 115.16, Thunderbird < 128.3, and Thunderbird < 131. | ||||
| CVE-2024-9393 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-03 | 7.5 High |
| An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the `resource://pdf.js` origin. This could allow them to access cross-origin PDF content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Firefox ESR < 115.16, Thunderbird < 128.3, and Thunderbird < 131. | ||||
| CVE-2024-9392 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-03 | 9.8 Critical |
| A compromised content process could have allowed for the arbitrary loading of cross-origin pages. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Firefox ESR < 115.16, Thunderbird < 128.3, and Thunderbird < 131. | ||||
| CVE-2024-6609 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | 8.8 High |
| When almost out-of-memory an elliptic curve key which was never allocated could have been freed again. This vulnerability affects Firefox < 128 and Thunderbird < 128. | ||||
| CVE-2024-6602 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-11-03 | 9.8 Critical |
| A mismatch between allocator and deallocator could have led to memory corruption. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128. | ||||
| CVE-2024-11699 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-03 | 8.8 High |
| Memory safety bugs present in Firefox 132, Firefox ESR 128.4, and Thunderbird 128.4. 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 < 133, Firefox ESR < 128.5, Thunderbird < 133, and Thunderbird < 128.5. | ||||
| CVE-2024-11697 | 2 Mozilla, Redhat | 9 Firefox, Firefox Esr, Thunderbird and 6 more | 2025-11-03 | 8.8 High |
| When handling keypress events, an attacker may have been able to trick a user into bypassing the "Open Executable File?" confirmation dialog. This could have led to malicious code execution. 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 | 2025-11-03 | 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. | ||||
