CVE-2025-6430 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 6.1 Medium
When a file download is specified via the `Content-Disposition` header, that directive would be ignored if the file was included via a `&lt;embed&gt;` or `&lt;object&gt;` tag, potentially making a website vulnerable to a cross-site scripting attack. This vulnerability affects Firefox < 140, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-6429 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 6.5 Medium
Firefox could have incorrectly parsed a URL and rewritten it to the youtube.com domain when parsing the URL specified in an `embed` tag. This could have bypassed website security checks that restricted which domains users were allowed to embed. This vulnerability affects Firefox < 140, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-6425 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 4.3 Medium
An attacker who enumerated resources from the WebCompat extension could have obtained a persistent UUID that identified the browser, and persisted between containers and normal/private browsing mode, but not profiles. This vulnerability affects Firefox < 140, Firefox ESR < 115.25, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-6424 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-03 9.8 Critical
A use-after-free in FontFaceSet resulted in a potentially exploitable crash. This vulnerability affects Firefox < 140, Firefox ESR < 115.25, Firefox ESR < 128.12, Thunderbird < 140, and Thunderbird < 128.12.
CVE-2025-5986 2 Mozilla, Redhat 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more 2025-11-03 6.5 Medium
A crafted HTML email using mailbox:/// links can trigger automatic, unsolicited downloads of .pdf files to the user's desktop or home directory without prompting, even if auto-saving is disabled. This behavior can be abused to fill the disk with garbage data (e.g. using /dev/urandom on Linux) or to leak Windows credentials via SMB links when the email is viewed in HTML mode. While user interaction is required to download the .pdf file, visual obfuscation can conceal the download trigger. Viewing the email in HTML mode is enough to load external content. This vulnerability affects Thunderbird < 128.11.1 and Thunderbird < 139.0.2.
CVE-2025-5269 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-03 8.1 High
Memory safety bug present in Firefox ESR 128.10, and Thunderbird 128.10. 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 < 128.11 and Thunderbird < 128.11.
CVE-2025-5268 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-03 8.1 High
Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10. 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 < 139, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
CVE-2025-5267 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 5.4 Medium
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.
CVE-2025-5266 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 4.3 Medium

CVE-2025-5264 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 4.8 Medium
Due to insufficient escaping of the newline character 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 vulnerability affects Firefox < 139, Firefox ESR < 115.24, Firefox ESR < 128.11, Thunderbird < 139, and Thunderbird < 128.11.
