Is this vulnerability remotely exploitable?

It can be, if an attacker can obtain read/write access to the backup storage over the network (e.g., misconfigured S3 bucket or compromised account) and a privileged user or system later restores from that manipulated backup.

What level of access does an attacker need?

The attacker needs the ability to modify backup manifest files in the storage location used by Vitess, but does not need direct access to the running Vitess instances or production hosts. The restore process becomes the execution vector.

What is the safest general fix pattern?

Constrain decompression to trusted, fixed commands or a small allowlist and ensure that any values read from manifests are treated as data only, not executable command strings. Avoid constructing shell commands from untrusted input altogether.
