Dear subscribers

We just published a security update to the stable version 1.3. It primarily fixes a recently reported IMAP command injection vulnerability caused by insufficient input validation within the archive plugin. Details about the vulnerability are published under CVE-2018-9846.

Additionally, we back-ported some minor fixes from the master branch which improve PHP 7.2 compatibility as well as PGP signing and key handling for those who use the Enigma plugin.

See the full changelog in the release notes on the Github download page: https://github.com/roundcube/roundcubemail/releases/tag/1.3.6

We strongly recommend to update all productive installations of Roundcube with this new version. Updates for older LTS versions will follow soon.

And as usual: please do backup your data before updating!

Best, Alec & Thomas
