Overview
Affected versions of this package are vulnerable to Command Injection via manipulation of backup manifest files. An attacker can execute arbitrary commands in the production deployment environment by restoring a crafted backup.
Workaround
This vulnerability can be mitigated by specifying a safe decompressor command (such as cat or tee) in the --external-decompressor flag for vttablet and vtbackup, which overrides any value specified in the manifest file.
