2) Information disclosure
EUVDB-ID: #VU107463
Risk: Medium
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2025-3522
CWE-ID:
CWE-200 - Exposure of sensitive information to an unauthorized actor
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a missing URL validation when processing the X-Mozilla-External-Attachment-URL header to handle externally hosted attachments. A remote attacker can send a specially crafted email to the victim that contains a link with an internally referenced document, such as "chrome://" or "chrome://" and force Thunderbird to share hashed Windows credentials with that URL, leading to information disclosure.
Update the affected package MozillaThunderbird to the latest version.

3) Spoofing attack
EUVDB-ID: #VU107465
Risk: Low
CVSSv4.0: 0.5 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N/E:U/U:Clear]
CVE-ID: CVE-2025-3523
CWE-ID:
CWE-451 - User Interface (UI) Misrepresentation of Critical Information (Clickjacking, spoofing)
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform spoofing attack.
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.
MitigationUpdate the affected package MozillaThunderbird to the latest version.
