### Impact If you're relying on blocking access to localhost using the default `0.0.0.0` filter this can be bypassed using other registered loopback devices (like `127.0.0.2` - `127.127.127.127`) ### Workaround You can block this bypass by manually adding the `127.0.0.0/8` CIDR range which will block access to any `127.X.X.X` ip instead of just `127.0.0.1`.

The czim/file-handling package before 1.5.0 and 2.x before 2.3.0 (used with PHP Composer) does not properly validate URLs within makeFromUrl and makeFromAny, leading to SSRF, and to directory traversal for the reading of local files.

A Server-Side Request Forgery (SSRF) vulnerability exists in berriai/litellm version 1.38.10. This vulnerability allows users to specify the `api_base` parameter when making requests to `POST /chat/completions`, causing the application to send the request to the domain specified by `api_base`. This request includes the OpenAI API key. A malicious user can set the `api_base` to their own domain and intercept the OpenAI API key, leading to unauthorized access and potential misuse of the API key.

A new security flaw has been addressed in the Apache OFBiz open-source enterprise resource planning (ERP) system that, if successfully exploited, could lead to unauthenticated remote code execution on Linux and Windows. The high-severity vulnerability, tracked as CVE-2024-45195 (CVSS score: 7.5), affects all versions of the software before 18.12.16. "An attacker with no valid

### Summary DNS rebinding is a method of manipulating resolution of domain names to let the initial DNS query hits an address and the second hits another one. For instance the host `make-190.119.176.200-rebind-127.0.0.1-rr.1u.ms` would be initially resolved to `190.119.176.200` and the next DNS issue to `127.0.0.1`. Please notice the following in the latest codebase: ```python def is_private_url(url: str): """ Raises exception if url is private :param url: url to check """ hostname = urlparse(url).hostname if not hostname: # Unable to find hostname in url return True ip = socket.gethostbyname(hostname) return ipaddress.ip_address(ip).is_private ``` As you can see, during the call to `is_private_url()` the initial DNS query would be issued by `ip = socket.gethostbyname(hostname)` to an IP (public one) and then due to DNS Rebinding, the next GET request would goes to the private one. ### PoC ```python from flask import Flask, requ...

### Summary The second argument to `RestRequest.AddHeader` (the header value) is vulnerable to CRLF injection. The same applies to `RestRequest.AddOrUpdateHeader` and `RestClient.AddDefaultHeader`. ### Details The way HTTP headers are added to a request is via the `HttpHeaders.TryAddWithoutValidation` method: <https://github.com/restsharp/RestSharp/blob/777bf194ec2d14271e7807cc704e73ec18fcaf7e/src/RestSharp/Request/HttpRequestMessageExtensions.cs#L32> This method does not check for CRLF characters in the header value. This means that any headers from a `RestSharp.RequestHeaders` object are added to the request in such a way that they are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. ### PoC The below example code creates a console app that takes one command line variable "api key" and then makes a request to some status page with the provided key inse...

The `req` library is a widely used HTTP library in Go. However, it does not handle malformed URLs effectively. As a result, after parsing a malformed URL, the library may send HTTP requests to unexpected destinations, potentially leading to security vulnerabilities or unintended behavior in applications relying on this library for handling HTTP requests. Despite developers potentially utilizing the `net/url` library to parse malformed URLs and implement blocklists to prevent HTTP requests to listed URLs, inconsistencies exist between how the `net/url` and `req` libraries parse URLs. These discrepancies can lead to the failure of defensive strategies, resulting in potential security threats such as Server-Side Request Forgery (SSRF) and Remote Code Execution (RCE).
