Rails Active Storage has possible glob injection in its DiskService
🔗 CVE IDs covered (1)
📋 Description
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.
