Dear AiiDA users,
We released the patch release v2.7.3 with important fixes to the transport and scheduler modules used in the CalcJob (for details please see the CHANGELOG.md). We strongly encourage you to upgrade to v2.7.3 from any v2.7.x release due to a security issue that can be exploited when using the ssh_async transport plugin with the openssh backend using OpenSSH version < 9.0. In this case a shell injection is possible by users who have write permission to the same disk space that your workflow is accessing. So if you are using a 2.7.x version and use the ssh_async transport plugin with the openssh backend, please upgrade immediately.
Best
The AiiDA team
