CVE-2025-3932
CVSS v2.0
7.8
High
| Vector | AV:N/AC:L/Au:N/C:C/I:N/A:N |
Name of the Vulnerable Software and Affected Versions:
Thunderbird versions prior to 128.10.1
Thunderbird versions prior to 138.0.1
Description:
The issue allowed an attacker to craft an email that showed a tracking link as an attachment. When the user attempted to open the attachment, Thunderbird automatically accessed the link. The configuration to block remote content did not prevent this behavior. The problem has been fixed to prevent access to web pages listed in the X-Mozilla-External-Attachment-URL header of an email.
Recommendations:
For versions prior to 128.10.1, update to version 128.10.1 or later to resolve the issue.
For versions prior to 138.0.1, update to version 138.0.1 or later to resolve the issue.
Fix
Authentication Bypass Using an Alternate Path or Channel
