| Doc Text: |
A flaw was found in Active Storage, a component of Rails applications. This vulnerability occurs because Active Storage's `DiskService#delete_prefixed` function does not properly escape glob metacharacters when processing blob keys. A remote attacker could exploit this by providing a specially crafted blob key, potentially leading to the deletion of unintended files from the storage directory. This could result in a data loss.
