Astra Linux – Vulnerability in Puma

Puma is a web server for Ruby/Rack applications built for parallelism. Prior to version 6.4.2, Puma exhibited incorrect behavior when parsing chunked transfer encoding bodies, allowing HTTP request smuggling. The fixed versions limit the size of chunk extensions. Without this limitation, an...

Astra Linux – Vulnerability in Puma

Puma is a Ruby/Rack web server designed for parallelism. In affected versions, clients could manipulate values set by intermediate proxies such as X-Forwarded-For by providing a version of the header with an underscore . Any users who rely on proxy-defined headers are affected. Versions...

Astra Linux – Vulnerability in Puma

Puma is a Ruby/Rack web server designed for parallelism. Prior to versions 6.3.1 and 5.6.7, Puma exhibited incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers, which could allow HTTP request smuggling. The severity of this issue depends heavily ...

Astra Linux – Vulnerability in Puma

Puma is a Ruby/Rack web server designed for parallelism. Prior to version 5.6.2 of Puma, Puma might not always call close on the response body. Before version 7.0.2.2 of Rails, Rails relied on the response body being closed in order for its CurrentAttributes implementation to work correctly. The...

Astra Linux – Vulnerability in Puma

Puma is an HTTP 1.1 server for Ruby/Rack applications. Prior to versions 5.5.1 and 4.3.9, using “puma” with a proxy that forwards HTTP header values containing the LF character could lead to HTTP request smuggling. A client could secretly send a request through a proxy, causing the proxy to send ...

CVE-2026-47736

A flaw was found in Puma, a Ruby/Rack web server. When PROXY protocol v1 support is enabled, a remote attacker can continuously send data without proper termination. This causes the server to consume an increasing amount of memory and CPU resources, leading to a Denial of Service DoS where the...

CVE-2026-47737

A flaw was found in Puma, a Ruby/Rack web server. When setremoteaddress proxyprotocol: :v1 is enabled and persistent connections are used, Puma incorrectly re-parses PROXY protocol headers after each keep-alive request on the same connection. This allows a remote attacker to inject a second PROXY...
