CVE-2025-2830: 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. CVE-2025-3523: 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. Firefox 137.0.2: https://www.mozilla.org/en-US/security/advisories/mfsa2025-25/ Thunderbird 137.0.2: https://www.mozilla.org/en-US/security/advisories/mfsa2025-26/ Thunderbird 128.9.2: https://www.mozilla.org/en-US/security/advisories/mfsa2025-27/
Disregard the two CVEs here, they do not affect Firefox. Sorry!
