Description
Active Storage allows users to attach cloud and local files in Rails applications. Prior to versions 8.1.2.1, 8.0.4.1, and 7.2.3.1, 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. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
Affected configurations
• rubyonrails rails (< 7.2.3.1)
• rubyonrails rails (>= 8.0.0 < 8.0.4.1)
• rubyonrails rails (>= 8.1.0 < 8.1.2.1)
