Incus before version 7.2.0 contains a vulnerability where improper validation of the user-supplied backup compression algorithm allows argument injection. This flaw enables an attacker to inject additional command-line arguments to the compression tool, leading to arbitrary file writes on the host system and potentially arbitrary command execution. The vulnerability arises because only the first token of the compression algorithm is validated against an allowlist, while extra arguments are passed unchecked to the compressor command. A proof-of-concept demonstrates writing a malicious cron job file to the host, enabling remote code execution.
