Debian Security Advisory DSA-4922-1 security@debian.org

- - -------------------------------------------------------------------------
Package : hyperkitty
CVE ID : CVE-2021-33038
Amir Sarabadani and Kunal Mehta discovered that the import functionality
of Hyperkitty, the web user interface to access Mailman 3 archives, did
not restrict the visibility of private archives during the import, i.e.
that during the import of a private Mailman 2 archive the archive was
publicly accessible until the import completed.
For the stable distribution (buster), this problem has been fixed in
version 1.2.2-1+deb10u1.
We recommend that you upgrade your hyperkitty packages.
For the detailed security status of hyperkitty please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/hyperkitty
