rubygem-rack: Rack QueryParser has an unsafe default allowing params_limit bypass via semicolon-separated parameters

An unsafe default behavior in Rack::QueryParser allows bypass of the paramslimit parameter count restriction when query string parameters are delimited by semicolons ; rather than ampersands &. The parser counts only & when enforcing the limit, while still splitting on both & and ;. As a result, ...

The vulnerability of the Rack module interface of the Ruby programming language interpreter is related to the fact that application does not properly control consumption of internal resources in the function "Rack::QueryParser" function. Exploitation of the vulnerability could allow an attacker...

UBUNTU-CVE-2025-61919

Rack is a modular Ruby web server interface. Prior to versions 2.2.20, 3.1.18, and 3.2.3, Rack::RequestPOST reads the entire request body into memory for Content-Type: application/x-www-form-urlencoded, calling rack.input.readnil without enforcing a length or cap. Large request bodies can therefo...

GHSA-6XW4-3V39-52MM Rack is vulnerable to a memory-exhaustion DoS through unbounded URL-encoded body parsing

Summary Rack::RequestPOST reads the entire request body into memory for Content-Type: application/x-www-form-urlencoded, calling rack.input.readnil without enforcing a length or cap. Large request bodies can therefore be buffered completely into process memory before parsing, leading to denial of...

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...
