CVE-2024-53975 1 Mozilla 1 Firefox 2025-10-28 N/A 5.4 MEDIUM
Accessing a non-secure HTTP site that uses a non-existent port may cause the SSL padlock icon in the location URL bar to, misleadingly, appear secure. This vulnerability affects Firefox for iOS < 133.
CVE-2019-11707 1 Mozilla 2 Firefox, Thunderbird 2025-10-27 7.5 HIGH 8.8 HIGH
A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in Array.pop. This can allow for an exploitable crash. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 60.7.1, Firefox < 67.0.3, and Thunderbird < 60.7.2.
CVE-2019-11708 1 Mozilla 2 Firefox, Thunderbird 2025-10-27 10.0 HIGH 10.0 CRITICAL
Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxed parent process opening web content chosen by a compromised child process. When combined with additional vulnerabilities this could result in executing arbitrary code on the user's computer. This vulnerability affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
CVE-2023-4863 9 Bandisoft, Bentley, Debian and 6 more 12 Honeyview, Seequent Leapfrog, Debian Linux and 9 more 2025-10-24 N/A 8.8 HIGH
Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)
CVE-2023-5217 8 Apple, Debian, Fedoraproject and 5 more 11 Ipados, Iphone Os, Debian Linux and 8 more 2025-10-24 N/A 8.8 HIGH
Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
CVE-2013-1690 6 Canonical, Debian, Mozilla and 3 more 15 Ubuntu Linux, Debian Linux, Firefox and 12 more 2025-10-22 9.3 HIGH 8.8 HIGH
Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location.
CVE-2013-1675 5 Canonical, Debian, Mozilla and 2 more 18 Ubuntu Linux, Debian Linux, Firefox and 15 more 2025-10-22 4.3 MEDIUM 6.5 MEDIUM
Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 do not properly initialize data structures for the nsDOMSVGZoomEvent::mPreviousScale and nsDOMSVGZoomEvent::mNewScale functions, which allows remote attackers to obtain sensitive information from process memory via a crafted web site.
CVE-2010-3765 1 Mozilla 3 Firefox, Seamonkey, Thunderbird 2025-10-22 9.3 HIGH 9.8 CRITICAL
Mozilla Firefox 3.5.x through 3.5.14 and 3.6.x through 3.6.11, Thunderbird 3.1.6 before 3.1.6 and 3.0.x before 3.0.10, and SeaMonkey 2.x before 2.0.10, when JavaScript is enabled, allows remote attackers to execute arbitrary code via vectors related to nsCSSFrameConstructor::ContentAppended, the appendChild method, incorrect index tracking, and the creation of multiple frames, which triggers memory corruption, as exploited in the wild in October 2010 by the Belmoo malware.
CVE-2015-4495 6 Canonical, Mozilla, Opensuse and 3 more 15 Ubuntu Linux, Firefox, Firefox Os and 12 more 2025-10-22 4.3 MEDIUM 8.8 HIGH
The PDF reader in Mozilla Firefox before 39.0.3, Firefox ESR 38.x before 38.1.1, and Firefox OS before 2.2 allows remote attackers to bypass the Same Origin Policy, and read arbitrary files or gain privileges, via vectors involving crafted JavaScript code and a native setter, as exploited in the wild in August 2015.
CVE-2025-11713 1 Mozilla 2 Firefox, Thunderbird 2025-10-20 N/A 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 Firefox running on other operating systems. This vulnerability affects Firefox < 144, Firefox ESR < 140.4, Thunderbird < 144, and Thunderbird < 140.4.
CVE-2025-11716 2 Google, Mozilla 3 Android, Firefox, Thunderbird 2025-10-16 N/A 6.5 MEDIUM
Links in a sandboxed iframe could open an external app on Android without the required "allow-" permission. This vulnerability affects Firefox < 144 and Thunderbird < 144.
CVE-2025-11719 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-10-15 N/A 9.8 CRITICAL
Starting in Firefox 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-2025-11717 2 Google, Mozilla 2 Android, Firefox 2025-10-15 N/A 9.1 CRITICAL
When switching between Android apps using the card carousel Firefox shows a black screen as its card image when a password-related screen was the last one being used. Prior to Firefox 144 the password edit screen was visible. This vulnerability affects Firefox < 144.
CVE-2025-11718 2 Google, Mozilla 2 Android, Firefox 2025-10-15 N/A 6.5 MEDIUM
When the address bar was hidden due to scrolling on Android, a malicious page could create a fake address bar to fool the user in response to a visibilitychange event This vulnerability affects Firefox < 144.
CVE-2025-11720 2 Google, Mozilla 2 Android, Firefox 2025-10-15 N/A 8.1 HIGH
The Firefox and Firefox Focus UI for the Android custom tab feature only showed the "site" that was loaded, not the full hostname. User supplied content hosted on a subdomain of a site could have been used to fool a user into thinking it was content from a different subdomain of that site. This vulnerability affects Firefox < 144.
CVE-2025-11721 1 Mozilla 2 Firefox, Thunderbird 2025-10-15 N/A 9.8 CRITICAL
Memory safety bug present in Firefox 143 and Thunderbird 143. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox < 144 and Thunderbird < 144.
CVE-2023-0163 1 Mozilla 1 Convict 2025-10-15 N/A 8.4 HIGH
Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') vulnerability in Mozilla Convict. This allows an attacker to inject attributes that are used in other components, or to override existing attributes with ones that have incompatible type, which may lead to a crash. The main use case of Convict is for handling server-side configurations written by the admins owning the servers, and not random users. So it's unlikely that an admin would deliberately sabotage their own server. Still, a situation can happen where an admin not knowledgeable about JavaScript could be tricked by an attacker into writing the malicious JavaScript code into some config files. This issue affects Convict: before 6.2.4.
CVE-2023-1521 1 Mozilla 1 Sccache 2025-10-15 N/A 7.8 HIGH
On Linux the sccache client can execute arbitrary code with the privileges of a local sccache server, by preloading the code in a shared library passed to LD_PRELOAD. If the server is run as root (which is the default when installing the snap package https://snapcraft.io/sccache ), this means a user running the sccache client can get root privileges.
CVE-2025-11153 1 Mozilla 1 Firefox 2025-10-13 N/A 7.5 HIGH
JIT miscompilation in the JavaScript Engine: JIT component. This vulnerability affects Firefox < 143.0.3.
