Background

Hyperkitty is a web user interface that provides access to Mailman 3 archives. It allows users to browse, search, and interact with mailing list archives. This vulnerability affects Hyperkitty version 1.2.2-1+deb10u1 and earlier.

Vulnerability Detail

The import functionality of Hyperkitty did not restrict the visibility of private archives during the import process. This means that when importing a private Mailman 2 archive, the archive was publicly accessible until the import completed. This could lead to unauthorized access to sensitive information during the import process.

How To Fix

Minimum fixed version

1.2.2-1+deb10u1

This is the first release that contains the fix.

To mitigate this vulnerability, it is recommended to upgrade to the latest version of the hyperkitty package. For further support on vulnerability remediation, please contact DevNack.com.
