rails: Active Storage allows users to attach cloud and local files in Rails applications
CVE-2026-33658 is fixed in rails on 1 platform, first by DEBIAN-CVE-2026-33658, released March 26, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
