CVE-2026-33202

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.
