GHSA-73f9-jhhh-hr5m
Rails Active Storage has possible glob injection in its DiskService
Quick fix
GHSA-73f9-jhhh-hr5m — activestorage: upgrade to the fixed version with the command below.
bundle update activestorageDetails
### 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.
