CVE-2025-2830 2 Mozilla, Redhat 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more 2025-06-18 6.3 Medium
By crafting a malformed file name for an attachment in a multipart message, an attacker can trick Thunderbird into including a directory listing of /tmp when the message is forwarded or edited as a new message. This vulnerability could allow attackers to disclose sensitive information from the victim's system. This vulnerability is not limited to Linux; similar behavior has been observed on Windows as well. This vulnerability affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2.
CVE-2025-3522 2 Mozilla, Redhat 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more 2025-06-18 6.3 Medium
Thunderbird processes the X-Mozilla-External-Attachment-URL header to handle attachments which can be hosted externally. When an email is opened, Thunderbird accesses the specified URL to determine file size, and navigates to it when the user clicks the attachment. Because the URL is not validated or sanitized, it can reference internal resources like chrome:// or SMB share file:// links, potentially leading to hashed Windows credential leakage and opening the door to more serious security issues. This vulnerability affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2.
CVE-2023-5496 2 Mozilla, Translator Poqdev Add-on Project 2 Firefox, Translator Poqdev Add-on 2025-06-16 3.1 Low

CVE-2025-2817 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-06-13 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-2025-3523 2 Mozilla, Redhat 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more 2025-06-13 6.4 Medium
When an email contains multiple attachments with external links via the X-Mozilla-External-Attachment-URL header, only the last link is shown when hovering over any attachment. Although the correct link is used on click, the misleading hover text could trick users into downloading content from untrusted sources. This vulnerability affects Thunderbird < 137.0.2 and Thunderbird < 128.9.2.
CVE-2023-5758 1 Mozilla 1 Firefox 2025-06-12 6.1 Medium
