Server-Side Request Forgery (SSRF)
A Server Side Request Forgery (SSRF) in the Data Import module in Heartex - Label Studio Community Edition versions prior to 1.6.0rc1 allows an authenticated user to access arbitrary files on the system. Furthermore, self-registration is enabled by default in these versions of Label Studio enabling a remote attacker to create a new account and then exploit the SSRF.
CWE-918 - Server-Side Request Forgery (SSRF)
Server-side request forgery (SSRF) is a weakness that allows an attacker to send an arbitrary request, making it appear that the request was sent by the server. This request may bypass a firewall that would normally prevent direct access to the URL. The impact of this vulnerability can vary from unauthorized access to files and sensitive information to remote code execution.
