The vulnerability of HTTP servers for Ruby/Rack applications developed with Puma arises from incorrect handling of characters such as CR, LF, /r, and /n before data is inserted into HTTP headers. This allows attackers to perform cross-site scripting attacks.

The vulnerability of HTTP servers for Ruby/Rack applications developed with Puma is related to the improper elimination of characters CR, LF, /r, and /n before data is entered into the HTTP headers. Exploiting this vulnerability allows a remote attacker to perform cross-site scripting attacks...

netty: HTTP request smuggling

A HTTP smuggling flaw was found in HttpObjectDecoder.java in Netty in versions prior to version 4.1.44. HTTP headers with an invalid fold, in this case CRLF carriage return, line feed without being followed by SP space or HTAB horizontal tab, result in situations where headers can be misread. Dat...
