Vulnerability	Vulnerable Version
M HTTP Request Smuggling Affected versions of this package are vulnerable to HTTP Request Smuggling due to improper handling of `pywsgi` `Input._send_100_continue`. An attacker could extract data or compromise data integrity by sending a request with an `Expect: 100-continue` header. How to fix HTTP Request Smuggling? Upgrade `gevent` to version 25.4.1 or higher.	[,25.4.1)
H Race Condition Affected versions of this package are vulnerable to Race Condition when the fallback socketpair implementation is used on platforms that lack native support and the vulnerable function does not properly authenticate the connected sockets. An attacker must be able to predict the address and port and establish a connection before the legitimate client. How to fix Race Condition? Upgrade `gevent` to version 24.10.1 or higher.	[,24.10.1)
C Trusting HTTP Permission Methods on the Server Side Affected versions of this package are vulnerable to Trusting HTTP Permission Methods on the Server Side when the `gevent.pywsgi` function is used. An attacker can craft invalid trailers in chunked requests on keep-alive connections that might appear as two requests to `gevent.pywsgi`. This could potentially bypass checks if an upstream server is filtering incoming requests based on paths or header fields and simply passing trailers through without validating them. An attacker could escalate privileges on the system via a crafted script to the WSGIServer component. Note: If the upstream server validated that the trailers meet the HTTP specification, this could not occur, because characters that are required in an HTTP request, like a space, are not allowed in trailers. How to fix Trusting HTTP Permission Methods on the Server Side? Upgrade `gevent` to version 23.9.0 or higher.	[,23.9.0)
M Information Exposure Affected versions of `gevent` are vulnerable to Information Exposure. The pywsgi `environ` dict print the entire WSGI environment by default which could have lead to information Exposure. How to fix Information Exposure? Upgrade `gevent` to version 1.2a1 or higher.	[,1.2a1)
