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 version 5.6.2 of Puma, Puma might not always call close on the response body. Before version 7.0.2.2, Rails relied on the response body being closed in order for its CurrentAttributes implementation to work correctly. The combinati...

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 an HTTP 1.1 server for Ruby/Rack applications. The fix for CVE-2019-16770 was incomplete. The original fix only protected existing connections that had already been accepted; it did not prevent new connections from being blocked by greedy persistent-connections that saturated all threads ...

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 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 an HTTP 1.1 server for Ruby/Rack applications. Before 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 a...

SUSE CVE-2026-47737

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-2026-47737

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...

PT-2026-47579

Impact PROXY protocol support for Puma was added in version 5.5.0. When PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer. It waits for "r " to determine whether a PROXY v1 line is present. If an attacker opens a TCP connection and continuously sends bytes...
