Astra Linux – Vulnerability in Ruby-Rack

A security vulnerability exists in versions of Rack 2.2.3 and Rack 2.1.4, where reliance on cookies without validation/integrity checks allows an attacker to forge a secure or host-only cookie prefix...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial-of-service vulnerability ReDos, degree 2 polynomial. This vulnerability has been fixed in 3.0.9.1 and 2.2.8.1...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. In versions 3.0.0.beta1 through 3.1.21, and from 3.2.0 through 3.2.6, Rack::Multipart::Parserhandlemimehead parsed quoted multipart parameters such as Content-Disposition: form-data; name="..." using repeated Stringindex searches combined with...

Astra Linux – Vulnerability in Ruby-Rack

A sequence injection vulnerability exists in Rack versions 2.0.9.1, 2.1.4.1, and 2.2.3.1. This vulnerability could allow for shell escapes in the Lint and CommonLogger components of Rack...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Multipart::Parser only wrapped the request body using BoundedIO when the CONTENTLENGTH header was present. When a multipart/form-data request was sent without a Content-Length header, such as with HTTP...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. Vulnerable applications will use the Rack::File middleware or the...

Astra Linux – Vulnerability in Ruby-Rack

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 buffered the entire multipart preamble bytes before the first boundary in memory, without any size limit. This caused significant memory usage and potential process termination due...

Astra Linux – Vulnerability in Ruby-Rack

There is a DoS vulnerability in Rack versions v3.0.4.2, v2.2.6.3, v2.1.4.3, and v2.0.9.3, particularly in the Multipart MIME parsing code. This vulnerability could allow an attacker to craft requests that can be abused to cause the multipart parsing to take longer than expected...

Astra Linux – Vulnerability in Puma

Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When using Puma behind a proxy that does not properly validate that the incoming HTTP requests comply with the RFC7230 standard, Puma and the frontend proxy may disagree about where the requests start and...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, Rack::Directory generated an HTML directory index where each file entry was rendered as a clickable link. If a file existed on the disk whose basename started with “javascript:”, such as “javascript:alert1”,...

Astra Linux – Vulnerability in Ruby-Rack

Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, the path check for Rack::Directory used a string prefix match on the expanded path. A request like /../rootexample/ could escape the configured root if the target path started with the root string, allowing...

CVE-2026-47737 Puma PROXY Protocol v1 Accepts Repeated Protocol Headers on Persistent Connections

Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, Puma is vulnerable to source IP spoofing when setremoteaddress proxyprotocol: :v1 is enabled and persistent connections are used because Puma incorrectly re-parses PROXY protocol headers after each keep-alive...

CVE-2026-47736: Uncontrolled Resource Consumption

Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, when PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer while waiting for CRLF to determine whether a PROXY v1 line is present, allowing an attacker that continuously sends...

The vulnerability of the Rack::Request component in the Ruby programming language’s Rack web server module allows attackers to circumvent existing security restrictions.

The vulnerability of the Rack::Request component in the Ruby-based Rack web server module interface is related to insufficient validation of input data. Exploiting this vulnerability allows an attacker to bypass existing security restrictions remotely...
