GHSA-WPV5-97WM-HP9C Rack's multipart parser buffers unbounded per-part headers, enabling DoS (memory exhaustion)
Summary Rack::Multipart::Parser can accumulate unbounded data when a multipart part’s header block never terminates with the required blank line CRLFCRLF. The parser keeps appending incoming bytes to memory without a size cap, allowing a remote attacker to exhaust memory and cause a denial of...
Rack: Multipart parser buffers large non‑file fields entirely in memory, enabling DoS (memory exhaustion)
Summary Rack::Multipart::Parser stores non-file form fields parts without a filename entirely in memory as Ruby String objects. A single large text field in a multipart/form-data request hundreds of megabytes or more can consume equivalent process memory, potentially leading to out-of-memory OOM...
Rack's unbounded multipart preamble buffering enables DoS (memory exhaustion)
Summary Rack::Multipart::Parser buffers the entire multipart preamble bytes before the first boundary in memory without any size limit. A client can send a large preamble followed by a valid boundary, causing significant memory use and potential process termination due to out-of-memory OOM...

Allocation of Resources Without Limits or Throttling
Overview rack is a minimal, modular and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between the so-called middleware into a singl...

CVE-2025-61772
Rack’s CVE-2025-61772 affects Rack::Multipart::Parser, which can accumulate unbounded per-part headers if a multipart part header never ends with a blank line. This leads to memory exhaustion and DoS on affected versions prior to 2.2.19, 3.1.17, and 3.2.2. The fix caps per-part header size (e.g.,...
