Rails Active Storage has possible glob injection in its DiskService
### Impact Active Storage's `DiskService#delete_prefixed` passes blob keys directly to `Dir.glob` without escaping glob metacharacters. If a blob key contains attacker-controlled input or custom-generated keys with glob metacharacters, it may be possible to delete unintended files from the storage directory. ### Releases The fixed releases are available at the normal locations.
