Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs). This is the source code release.

### Summary Tornado’s `curl_httpclient.CurlAsyncHTTPClient` class is vulnerable to CRLF (carriage return/line feed) injection in the request headers. ### Details When an HTTP request is sent using `CurlAsyncHTTPClient`, Tornado does not reject carriage return (\r) or line feed (\n) characters in the request headers. As a result, if an application includes an attacker-controlled header value in a request sent using `CurlAsyncHTTPClient`, the attacker can inject arbitrary headers into the request or cause the application to send arbitrary requests to the specified server. This behavior differs from that of the standard `AsyncHTTPClient` class, which does reject CRLF characters. This issue appears to stem from libcurl's (as well as pycurl's) lack of validation for the [`HTTPHEADER`](https://curl.se/libcurl/c/CURLOPT_HTTPHEADER.html) option. libcurl’s documentation states: > The headers included in the linked list must not be CRLF-terminated, because libcurl adds CRLF after each header...

### Summary When Tornado receives a request with two `Transfer-Encoding: chunked` headers, it ignores them both. This enables request smuggling when Tornado is deployed behind a proxy server that emits such requests. [Pound](https://en.wikipedia.org/wiki/Pound_(networking)) does this. ### PoC 0. Install Tornado. 1. Start a simple Tornado server that echoes each received request's body: ```bash cat << EOF > server.py import asyncio import tornado class MainHandler(tornado.web.RequestHandler): def post(self): self.write(self.request.body) async def main(): tornado.web.Application([(r"/", MainHandler)]).listen(8000) await asyncio.Event().wait() asyncio.run(main()) EOF python3 server.py & ``` 2. Send a valid chunked request: ```bash printf 'POST / HTTP/1.1\r\nTransfer-Encoding: chunked\r\n\r\n1\r\nZ\r\n0\r\n\r\n' | nc localhost 8000 ``` 3. Observe that the response is as expected: ``` HTTP/1.1 200 OK Server: TornadoServer/6.3.3 Content-Type: text/html; charset=UTF-8...

A Server-Side Request Forgery (SSRF) vulnerability exists in the Web Research Retriever component of langchain-ai/langchain version 0.1.5. The vulnerability arises because the Web Research Retriever does not restrict requests to remote internet addresses, allowing it to reach local addresses. This flaw enables attackers to execute port scans, access local services, and in some scenarios, read instance metadata from cloud environments. The vulnerability is particularly concerning as it can be exploited to abuse the Web Explorer server as a proxy for web attacks on third parties and interact with servers in the local network, including reading their response data. This could potentially lead to arbitrary code execution, depending on the nature of the local services. The vulnerability is limited to GET requests, as POST requests are not possible, but the impact on confidentiality, integrity, and availability is significant due to the potential for stolen credentials and state-changing int...
