### Summary The various header-related Refit attributes (Header, HeaderCollection and Authorize) are vulnerable to CRLF injection. ### Details The way HTTP headers are added to a request is via the `HttpHeaders.TryAddWithoutValidation` method: <https://github.com/reactiveui/refit/blob/258a771f44417c6e48e103ac921fe4786f3c2a1e/Refit/RequestBuilderImplementation.cs#L1328> This method does not check for CRLF characters in the header value. This means that any headers added to a refit request 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 (a bearer token) and then makes a request to some status page with the provided token inserted in the "Authorization" header: ```c# using Refit; internal class Program { private static void Main(string[] args) { ...

IBM Security Verify Access versions prior to 10.0.8 suffer from authentication bypass, reuse of private keys, local privilege escalation, weak settings, outdated libraries, missing password, hardcoded secrets, remote code execution, missing authentication, null pointer dereference, and lack of privilege separation vulnerabilities.

SmartAgent version 1.1.0 suffers from a server-side request forgery vulnerability.

Versions of the package sinatra from 0.0.0 are vulnerable to Reliance on Untrusted Inputs in a Security Decision via the X-Forwarded-Host (XFH) header. When making a request to a method with redirect applied, it is possible to trigger an Open Redirect Attack by inserting an arbitrary address into this header. If used for caching purposes, such as with servers like Nginx, or as a reverse proxy, without handling the X-Forwarded-Host header, attackers can potentially exploit Cache Poisoning or Routing-based SSRF.

WordPress Automatic plugin versions 3.92.0 and below proof of concept exploit that demonstrates path traversal and server-side request forgery vulnerabilities.

Qualitor versions 8.24 and below suffer from an unauthenticated server-side request forgery vulnerability.

Vulnhuntr is a Python static code analyzer that uses Claude AI to find and explain complex, multistep vulnerabilities.

### Summary The Butterfly framework uses the `java.net.URL` class to refer to (what are expected to be) local resource files, like images or templates. This works: "opening a connection" to these URLs opens the local file. However, if a `file:/` URL is directly given where a relative path (resource name) is expected, this is also accepted in some code paths; the app then fetches the file, from a remote machine if indicated, and uses it as if it was a trusted part of the app's codebase. This leads to multiple weaknesses and potential weaknesses: * An attacker that has network access to the application could use it to gain access to files, either on the the server's filesystem (path traversal) or shared by nearby machines (server-side request forgery with e.g. SMB). * An attacker that can lead or redirect a user to a crafted URL belonging to the app could cause arbitrary attacker-controlled JavaScript to be loaded in the victim's browser (cross-site scripting). * If an app is written ...
