| An attacker could have caused an out of bounds memory access using WebGL APIs, leading to memory corruption and a potentially exploitable crash. *This bug only affects Firefox and Thunderbird for macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 112, Firefox ESR < 102.10, and Thunderbird < 102.10. | |||||
| CVE-2023-23599 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-10-24 | N/A | 6.5 MEDIUM |
| When copying a network request from the developer tools panel as a curl command the output was not being properly sanitized and could allow arbitrary commands to be hidden within. This vulnerability affects Firefox < 109, Firefox ESR < 102.7, and Thunderbird < 102.7. | |||||
| CVE-2023-29535 | 1 Mozilla | 5 Firefox, Firefox Esr, Firefox Mobile and 2 more | 2026-10-24 | N/A | 6.5 MEDIUM |
| Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10. | |||||
| CVE-2023-34414 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-10-24 | N/A | 3.1 LOW |
| The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed. With the right timing the elicited clicks could land in that gap and activate the button that overrides the certificate error for that site. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12. | |||||
| CVE-2023-4045 | 2 Debian, Mozilla | 2 Debian Linux, Firefox | 2026-10-24 | N/A | 5.3 MEDIUM |

| When encoding data from an <code>inputStream</code> in <code>xpcom</code> the size of the input being encoded was not correctly calculated potentially leading to an out of bounds memory write. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. | |||||

| CVE-2023-23605 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-10-24 | N/A | 8.8 HIGH |
| Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and Firefox ESR 102.6. 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 < 109, Firefox ESR < 102.7, and Thunderbird < 102.7. | |||||

| A local attacker can trick the Mozilla Maintenance Service into applying an unsigned update file by pointing the service at an update file on a malicious SMB server. The update file can be replaced after the signature check, before the use, because the write-lock requested by the service does not work on a SMB server. *Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.* This vulnerability affects Firefox < 112, Firefox ESR < 102.10, and Thunderbird < 102.10. | |||||
