Rack 安全漏洞

Rack is a modular Ruby web server interface open-sourced by Rack. A security vulnerability exists in Rack versions prior to 2.2.20, 3.1.18, and 3.2.3, which stems from the possibility that Rack::Sendfile may bypass proxy access restrictions when handling specially crafted headers, leading to...

Rack has a Possible Information Disclosure Vulnerability

Summary A possible information disclosure vulnerability existed in Rack::Sendfile when running behind a proxy that supports x-sendfile headers such as Nginx. Specially crafted headers could cause Rack::Sendfile to miscommunicate with the proxy and trigger unintended internal requests, potentially...

Ruby Rack < 2.2.19 / 3.1.x < 3.1.17 / 3.2.x < 3.2.2 Multiple Vulnerabilities

The version of the Rack Ruby library installed on the remote host is prior to 2.2.19, 3.1.x prior to 3.1.17, or 3.2.x prior to 3.2.2. It is, therefore, affected by multiple vulnerabilities: - Rack::Multipart::Parser buffers the entire multipart preamble bytes before the first boundary in memory...

SUSE CVE-2025-61770

Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, 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...

SUSE CVE-2025-61771

Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, 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...

SUSE CVE-2025-61772

Rack is a modular Ruby web server interface. In versions prior to 2.2.19, 3.1.17, and 3.2.2, 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 witho...

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...
