The Wolfi security team deemed this advisory irrelevant for Wolfi:latest.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby3.4-rails-8.0 package and not the ruby3.4-rails-8.0 package as distributed by Wolfi.
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 proxy controller does not limit the number of byte ranges in an HTTP Range header. A request with thousands of small ranges causes disproportionate CPU usage compared to a normal request for the same file, possibly resulting in a DoS vulnerability. Versions 8.1.2.1, 8.0.4.1, and 7.2.3.1 contain a patch.
