NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby3.2-rails-8.1 package and not the ruby3.2-rails-8.1 package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

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.
