CVE-2025-6435 1 Mozilla 2 Firefox, Thunderbird 2026-04-20 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 was fixed in Firefox 140 and Thunderbird 140.
CVE-2025-6436 1 Mozilla 2 Firefox, Thunderbird 2026-04-20 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 was fixed in Firefox 140 and Thunderbird 140.
CVE-2006-3677 2 Mozilla, Redhat 3 Firefox, Seamonkey, Enterprise Linux 2026-04-16 N/A
Mozilla Firefox 1.5 before 1.5.0.5 and SeaMonkey before 1.0.3 allows remote attackers to execute arbitrary code by changing certain properties of the window navigator object (window.navigator) that are accessed when Java starts up, which causes a crash that leads to code execution.

Mozilla Firefox 1.5 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via simultaneous XPCOM events, which causes a timer object to be deleted in a way that triggers memory corruption.
CVE-2006-3811 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Multiple vulnerabilities in Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via Javascript that leads to memory corruption, including (1) nsListControlFrame::FireMenuItemActiveEvent, (2) buffer overflows in the string class in out-of-memory conditions, (3) table row and column groups, (4) "anonymous box selectors outside of UA stylesheets," (5) stale references to "removed nodes," and (6) running the crypto.generateCRMFRequest callback on deleted context.
CVE-2006-3801 2 Mozilla, Redhat 3 Firefox, Seamonkey, Enterprise Linux 2026-04-16 N/A
Mozilla Firefox 1.5 before 1.5.0.5 and SeaMonkey before 1.0.3 does not properly clear a JavaScript reference to a frame or window, which leaves a pointer to a deleted object that allows remote attackers to execute arbitrary native code.
CVE-2006-3809 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows scripts with the UniversalBrowserRead privilege to gain UniversalXPConnect privileges and possibly execute code or obtain sensitive data by reading into a privileged context.
CVE-2006-3810 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in Mozilla Firefox 1.5 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to inject arbitrary web script or HTML via the XPCNativeWrapper(window).Function construct.
CVE-2006-3808 2 Mozilla, Redhat 3 Firefox, Seamonkey, Enterprise Linux 2026-04-16 N/A
Mozilla Firefox before 1.5.0.5 and SeaMonkey before 1.0.3 allows remote Proxy AutoConfig (PAC) servers to execute code with elevated privileges via a PAC script that sets the FindProxyForURL function to an eval method on a privileged object.
CVE-2006-3805 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
The Javascript engine in Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 might allow remote attackers to execute arbitrary code via vectors involving garbage collection that causes deletion of a temporary object that is still being used.
CVE-2006-3804 2 Mozilla, Redhat 3 Seamonkey, Thunderbird, Enterprise Linux 2026-04-16 N/A
Heap-based buffer overflow in Mozilla Thunderbird before 1.5.0.5 and SeaMonkey before 1.0.3 allows remote attackers to cause a denial of service (crash) via a VCard attachment with a malformed base64 field, which copies more data than expected due to an integer underflow.
CVE-2006-3806 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Multiple integer overflows in the Javascript engine in Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 might allow remote attackers to execute arbitrary code via vectors involving (1) long strings in the toSource method of the Object, Array, and String objects; and (2) unspecified "string function arguments."
CVE-2006-3802 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to hijack native DOM methods from objects in another domain and conduct cross-site scripting (XSS) attacks using DOM methods of the top-level object.
CVE-2006-1045 2 Mozilla, Redhat 2 Thunderbird, Enterprise Linux 2026-04-16 N/A
The HTML rendering engine in Mozilla Thunderbird 1.5, when "Block loading of remote images in mail messages" is enabled, does not properly block external images from inline HTML attachments, which could allow remote attackers to obtain sensitive information, such as application version or IP address, when the user reads the email and the external image is accessed.
CVE-2006-3803 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Race condition in the JavaScript garbage collection in Mozilla Firefox 1.5 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 might allow remote attackers to execute arbitrary code by causing the garbage collector to delete a temporary variable while it is still being used during the creation of a new Function object.
CVE-2006-3807 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-16 N/A
Mozilla Firefox before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to execute arbitrary code via script that changes the standard Object() constructor to return a reference to a privileged object and calling "named JavaScript functions" that use the constructor.
CVE-2026-2796 1 Mozilla 2 Firefox, Thunderbird 2026-04-15 9.8 Critical
JIT miscompilation in the JavaScript: WebAssembly component. This vulnerability was fixed in Firefox 148 and Thunderbird 148.
CVE-2024-9397 2 Mozilla, Redhat 9 Firefox, Firefox Esr, Thunderbird and 6 more 2026-03-02 6.1 Medium
A missing delay in directory upload UI could have made it possible for an attacker to trick a user into granting permission via clickjacking. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2026-24868 1 Mozilla 1 Firefox 2026-02-06 6.5 Medium
Mitigation bypass in the Privacy: Anti-Tracking component. This vulnerability affects Firefox < 147.0.2.
CVE-2026-0818 1 Mozilla 1 Thunderbird 2026-02-04 4.3 Medium
When a user explicitly requested Thunderbird to decrypt an inline OpenPGP message that was embedded in a text section of an email that was formatted and styled with HTML and CSS, then the decrypted contents were rendered in a context in which the CSS styles from the outer messages were active. If the user had additionally allowed loading of the remote content referenced by the outer email message, and the email was crafted by the sender using a combination of CSS rules and fonts and animations, then it was possible to extract the secret contents of the email. This vulnerability affects Thunderbird < 147.0.1 and Thunderbird < 140.7.1.
