CVE-2025-13020 1 Mozilla 2 Firefox, Firefox Esr 2025-11-25 8.8 High
Use-after-free in the WebRTC: Audio/Video component. This vulnerability affects Firefox < 145, Firefox ESR < 140.5, Thunderbird < 145, and Thunderbird < 140.5.
CVE-2025-13027 1 Mozilla 2 Firefox, Thunderbird 2025-11-25 8.1 High
Memory safety bugs present in Firefox 144 and Thunderbird 144. 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 < 145 and Thunderbird < 145.
CVE-2025-11719 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-14 9.8 Critical
Starting in Thunderbird 143, the use of the native messaging API by web extensions on Windows could lead to crashes caused by use-after-free memory corruption. This vulnerability affects Firefox < 144 and Thunderbird < 144.
CVE-2025-11713 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2025-11-14 8.1 High
Insufficient escaping in the “Copy as cURL” feature could have been used to trick a user into executing unexpected code on Windows. This did not affect the application when running on other operating systems. This vulnerability affects Firefox < 144, Firefox ESR < 140.4, Thunderbird < 144, and Thunderbird < 140.4.
CVE-2025-6436 1 Mozilla 2 Firefox, Thunderbird 2025-11-13 8.1 High
Memory safety bugs present in Firefox 139 and Thunderbird 139. 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 < 140 and Thunderbird < 140.
CVE-2025-6435 1 Mozilla 2 Firefox, Thunderbird 2025-11-13 8.1 High
If a user saved a response from the Network tab in Devtools using the Save As context menu option, that file may not have been saved with the `.download` file extension. This could have led to the user inadvertently running a malicious executable. This vulnerability affects Firefox < 140 and Thunderbird < 140.
CVE-2024-5696 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-06 8.6 High
By manipulating the text in an `&lt;input&gt;` tag, an attacker could have caused corrupt memory leading to a potentially exploitable crash. This vulnerability affects Firefox < 127, Firefox ESR < 115.12, and Thunderbird < 115.12.
CVE-2023-4421 1 Mozilla 1 Nss 2025-11-04 6.5 Medium
The NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key. The issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper. This vulnerability affects NSS < 3.61.
CVE-2023-5388 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-04 6.5 Medium
NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
CVE-2024-8384 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-04 9.8 Critical
The JavaScript garbage collector could mis-color cross-compartment objects if OOM conditions were detected at the right point between two passes. This could have led to memory corruption. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, Firefox ESR < 115.15, Thunderbird < 128.2, and Thunderbird < 115.15.
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-2024-8381 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-04 9.8 Critical
A potentially exploitable type confusion could be triggered when looking up a property name on an object being used as the `with` environment. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, Firefox ESR < 115.15, Thunderbird < 128.2, and Thunderbird < 115.15.
CVE-2024-6606 1 Mozilla 2 Firefox, Thunderbird 2025-11-04 8.2 High
Clipboard code failed to check the index on an array access. This could have led to an out-of-bounds read. This vulnerability affects Firefox < 128 and Thunderbird < 128.
CVE-2025-8028 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2025-11-04 9.8 Critical
On arm64, a WASM `br_table` instruction with a lot of entries could lead to the label being too far from the instruction causing truncation and incorrect computation of the branch address. This vulnerability affects Firefox < 141, Firefox ESR < 115.26, Firefox ESR < 128.13, Firefox ESR < 140.1, Thunderbird < 141, Thunderbird < 128.13, and Thunderbird < 140.1.
CVE-2025-8029 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2025-11-04 8.1 High
Thunderbird executed `javascript:` URLs when used in `object` and `embed` tags. This vulnerability affects Firefox < 141, Firefox ESR < 128.13, Firefox ESR < 140.1, Thunderbird < 141, Thunderbird < 128.13, and Thunderbird < 140.1.
CVE-2025-8036 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-04 8.1 High
Thunderbird cached CORS preflight responses across IP address changes. This allowed circumventing CORS with DNS rebinding. This vulnerability affects Firefox < 141, Firefox ESR < 140.1, Thunderbird < 141, and Thunderbird < 140.1.
CVE-2025-8037 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-04 9.1 Critical
Setting a nameless cookie with an equals sign in the value shadowed other cookies. Even if the nameless cookie was set over HTTP and the shadowed cookie included the `Secure` attribute. This vulnerability affects Firefox < 141, Firefox ESR < 140.1, Thunderbird < 141, and Thunderbird < 140.1.
CVE-2025-8030 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2025-11-04 8.1 High
Insufficient escaping in the “Copy as cURL” feature could potentially be used to trick a user into executing unexpected code. This vulnerability affects Firefox < 141, Firefox ESR < 128.13, Firefox ESR < 140.1, Thunderbird < 141, Thunderbird < 128.13, and Thunderbird < 140.1.
CVE-2025-8031 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2025-11-04 9.8 Critical
The `username:password` part was not correctly stripped from URLs in CSP reports potentially leaking HTTP Basic Authentication credentials. This vulnerability affects Firefox < 141, Firefox ESR < 128.13, Firefox ESR < 140.1, Thunderbird < 141, Thunderbird < 128.13, and Thunderbird < 140.1.
