|---|---|---|---|---|---|
| CVE-2025-5263 | 1 Mozilla | 1 Firefox | 2025-11-03 | N/A | 4.3 MEDIUM |
| Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. | |||||
| CVE-2025-4919 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.8 HIGH |
| An attacker was able to perform an out-of-bounds read or write on a JavaScript object by confusing array index sizes. This vulnerability affects Firefox < 138.0.4, Firefox ESR < 128.10.1, Firefox ESR < 115.23.1, Thunderbird < 128.10.2, and Thunderbird < 138.0.2. | |||||
| CVE-2025-4918 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 9.8 CRITICAL |
| An attacker was able to perform an out-of-bounds read or write on a JavaScript `Promise` object. This vulnerability affects Firefox < 138.0.4, Firefox ESR < 128.10.1, Firefox ESR < 115.23.1, Thunderbird < 128.10.2, and Thunderbird < 138.0.2. | |||||
| CVE-2025-4093 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.1 HIGH |
| Memory safety bug present in Firefox ESR 128.9, and Thunderbird 128.9. 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 ESR < 128.10 and Thunderbird < 128.10. | |||||
| CVE-2025-4091 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.1 HIGH |
| Memory safety bugs present in Firefox 137, Thunderbird 137, Firefox ESR 128.9, and Thunderbird 128.9. 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 < 138, Firefox ESR < 128.10, Thunderbird < 138, and Thunderbird < 128.10. | |||||
| CVE-2025-4087 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 4.8 MEDIUM |
| A vulnerability was identified in Thunderbird where XPath parsing could trigger undefined behavior due to missing null checks during attribute access. This could lead to out-of-bounds read access and potentially, memory corruption. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Thunderbird < 138, and Thunderbird < 128.10. | |||||
| CVE-2025-4084 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 5.7 MEDIUM |
| Due to insufficient escaping of the special characters in the "copy as cURL" feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. *This bug only affects Firefox for Windows. Other versions of Firefox are unaffected.* This vulnerability affects Firefox ESR < 128.10, Firefox ESR < 115.23, and Thunderbird < 128.10. | |||||
| CVE-2025-4083 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 9.1 CRITICAL |
| A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape. This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Firefox ESR < 115.23, Thunderbird < 138, and Thunderbird < 128.10. | |||||
| CVE-2025-4082 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 5.9 MEDIUM |
| Modification of specific WebGL shader attributes could trigger an out-of-bounds read, which, when chained with other vulnerabilities, could be used to escalate privileges. *This bug only affects Thunderbird for macOS. Other versions of Thunderbird are unaffected.* This vulnerability affects Firefox < 138, Firefox ESR < 128.10, Firefox ESR < 115.23, Thunderbird < 138, and Thunderbird < 128.10. | |||||
| CVE-2025-3932 | 1 Mozilla | 1 Thunderbird | 2025-11-03 | N/A | 6.5 MEDIUM |
| It was possible to craft an email that showed a tracking link as an attachment. If the user attempted to open the attachment, Thunderbird automatically accessed the link. The configuration to block remote content did not prevent that. Thunderbird has been fixed to no longer allow access to web pages listed in the X-Mozilla-External-Attachment-URL header of an email. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. | |||||
| CVE-2025-3909 | 1 Mozilla | 1 Thunderbird | 2025-11-03 | N/A | 6.5 MEDIUM |
| Thunderbird's handling of the X-Mozilla-External-Attachment-URL header can be exploited to execute JavaScript in the file:/// context. By crafting a nested email attachment (message/rfc822) and setting its content type to application/pdf, Thunderbird may incorrectly render it as HTML when opened, allowing the embedded JavaScript to run without requiring a file download. This behavior relies on Thunderbird auto-saving the attachment to /tmp and linking to it via the file:/// protocol, potentially enabling JavaScript execution as part of the HTML. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. | |||||
| CVE-2025-3875 | 1 Mozilla | 1 Thunderbird | 2025-11-03 | N/A | 7.5 HIGH |
| Thunderbird parses addresses in a way that can allow sender spoofing in case the server allows an invalid From address to be used. For example, if the From header contains an (invalid) value "Spoofed Name ", Thunderbird treats spoofed@example.com as the actual address. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. | |||||
| CVE-2025-3030 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.1 HIGH |
| Memory safety bugs present in Firefox 136, Thunderbird 136, Firefox ESR 128.8, and Thunderbird 128.8. 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 < 137, Firefox ESR < 128.9, Thunderbird < 137, and Thunderbird < 128.9. | |||||
| CVE-2025-3029 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 7.3 HIGH |
| A crafted URL containing specific Unicode characters could have hidden the true origin of the page, resulting in a potential spoofing attack. This vulnerability affects Firefox < 137, Firefox ESR < 128.9, Thunderbird < 137, and Thunderbird < 128.9. | |||||
| CVE-2025-3028 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 6.5 MEDIUM |
| JavaScript code running while transforming a document with the XSLTProcessor could lead to a use-after-free. This vulnerability affects Firefox < 137, Firefox ESR < 115.22, Firefox ESR < 128.9, Thunderbird < 137, and Thunderbird < 128.9. | |||||
| CVE-2025-2817 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.8 HIGH |
| 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-2025-9185 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.1 HIGH |
| Memory safety bugs present in Firefox ESR 115.26, Firefox ESR 128.13, Thunderbird ESR 128.13, Firefox ESR 140.1, Thunderbird ESR 140.1, Firefox 141 and Thunderbird 141. 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 < 142, Firefox ESR < 115.27, Firefox ESR < 128.14, Firefox ESR < 140.2, Thunderbird < 142, Thunderbird < 128.14, and Thunderbird < 140.2. | |||||
| CVE-2025-9181 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 6.5 MEDIUM |
| Uninitialized memory in the JavaScript Engine component. This vulnerability affects Firefox < 142, Firefox ESR < 128.14, Firefox ESR < 140.2, Thunderbird < 142, Thunderbird < 128.14, and Thunderbird < 140.2. | |||||
| CVE-2025-9180 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 8.1 HIGH |
| Same-origin policy bypass in the Graphics: Canvas2D component. This vulnerability affects Firefox < 142, Firefox ESR < 115.27, Firefox ESR < 128.14, Firefox ESR < 140.2, Thunderbird < 142, Thunderbird < 128.14, and Thunderbird < 140.2. | |||||
| CVE-2025-9179 | 1 Mozilla | 2 Firefox, Thunderbird | 2025-11-03 | N/A | 9.8 CRITICAL |
| An attacker was able to perform memory corruption in the GMP process which processes encrypted media. This process is also heavily sandboxed, but represents slightly different privileges from the content process. This vulnerability affects Firefox < 142, Firefox ESR < 115.27, Firefox ESR < 128.14, Firefox ESR < 140.2, Thunderbird < 142, Thunderbird < 128.14, and Thunderbird < 140.2. | |||||
