CVSS v3.1 |
| A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. |
| Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. This vulnerability affects Firefox < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Information disclosure in the Networking: Cache component. This vulnerability affects Firefox < 143, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3. |
| Integer overflow in the SVG component. This vulnerability affects Firefox < 143, Firefox ESR < 115.28, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3. |
| Incorrect boundary conditions in the JavaScript: GC component. This vulnerability affects Firefox < 143, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3. |
| Same-origin policy bypass in the Layout component. This vulnerability affects Firefox < 143, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3. |
| Sandbox escape due to undefined behavior, invalid pointer in the Graphics: Canvas2D component. This vulnerability affects Firefox < 143, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3. |
| Sandbox escape due to use-after-free in the Graphics: Canvas2D component. This vulnerability affects Firefox < 143, Firefox ESR < 140.3, Thunderbird < 143, and Thunderbird < 140.3. |
| Following the recent Chrome sandbox escape (CVE-2025-2783), various Firefox developers identified a similar pattern in our IPC code. A compromised child process could cause the parent process to return an unintentionally powerful handle, leading to a sandbox escape.
The original vulnerability was being exploited in the wild.
*This only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 136.0.4, Firefox ESR < 128.8.1, and Firefox ESR < 115.21.1. |
| Sandbox escape due to integer overflow in the Graphics: Canvas2D component. This vulnerability affects Firefox < 143.0.3. |
| Mitigation bypass in the Web Compatibility: Tooling component. This vulnerability affects Firefox < 143 and Thunderbird < 143. |
| Spoofing issue in the WebAuthn component in Firefox for Android. This vulnerability affects Firefox < 143 and Thunderbird < 143. |
| The frame iterator could get stuck in a loop when encountering certain wasm frames leading to incorrect stack traces. This vulnerability affects Firefox < 128 and Thunderbird < 128. |
| Form validation popups could capture escape key presses. Therefore, spamming form validation messages could be used to prevent users from exiting full-screen mode. This vulnerability affects Firefox < 128 and Thunderbird < 128. |
| Cookie storage for non-HTML temporary documents was being shared incorrectly with normal browsing content, allowing information from private tabs to escape Incognito mode even after the user closed all tabs This vulnerability affects Firefox for iOS < 143.1. |
