Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
