CVE-2025-59830 Rack QueryParser has an unsafe default allowing params_limit bypass via semicolon-separated parameters

Rack is a modular Ruby web server interface. Prior to version 2.2.18, Rack::QueryParser enforces its paramslimit only for parameters separated by &, while still splitting on both & and ;. As a result, attackers could use ; separators to bypass the parameter count limit and submit more parameters...
