Reported from https://github.com/lxc/incus/security/advisories/GHSA-v6mj-8pf4-hhw4 ### Summary 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. ### Details Incus validates `compression_algorithm` by parsing it into fields and checking only the first token against an allowlist: ```go fields, err :=…
