Original description
The description as published by the source.
Incus is a system container and virtual machine manager. Prior to version 7.1.0, improper validation of user-provided backup compression algorithm leads to argument injection in the constructed command line. This leads to an arbitrary file write on the host, possibly leading to arbitrary command execution. Version 7.1.0 patches the issue.
