CVE-2026-49103 Details
Description
Webmin before 2.640 does not safely construct a filename for saving of an attachment within the mailboxes component. This occurs in mailboxes/detachall.cgi.
A vulnerability exists in Webmin versions prior to 2.640 within the mailboxes component. The issue arises because the application does not properly sanitize filenames when saving attachments, particularly in the 'detachall.cgi' script. This flaw could potentially be exploited to manipulate file handling in an unintended manner.
Users can upgrade to Webmin version 2.641 or later, where this vulnerability has been addressed.
