txtdot is an HTTP proxy that parses only text, links, and pictures from pages, removing ads and heavy scripts. Starting in version 1.4.0 and prior to version 1.6.1, a Server-Side Request Forgery (SSRF) vulnerability in the /proxy route of txtdot allows remote attackers to use the server as a proxy to send HTTP GET requests to arbitrary targets and retrieve information in the internal network. Version 1.6.1 patches the issue.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
