Starting in version 3.1.0 and prior to version 3.1.16, there is a denial of service vulnerability in the Content-Disposition parsing component of Rack. This is very similar to the previous security issue CVE-2022-44571. Carefully crafted input can cause Content-Disposition header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. This header is used typically used in multipart parsing. Any applications that parse multipart posts using Rack (virtually all Rails applications) are impacted.

The flaw affects availability only (no confidentiality or integrity impact) and carries a modest CVSS 5.3 (A:L), making it inherently lower priority than issues enabling data access or code execution. Moreover, causing meaningful impact requires sustained volumes of crafted multipart requests to monopolize worker time, reducing its practical risk in typical server deployments.",
