CVE-2024-27927

Summary

CVE-2024-27927 is a vulnerability affecting the open source RSS feed generator, RSSHub, prior to version 1.0.0-master.a429472. This issue permits remote attackers to leverage the server as a proxy to send HTTP GET requests to arbitrary targets, potentially leading to serious consequences. The server may reveal its internal IP address, which could be hidden behind a Content Delivery Network (CDN). Furthermore, the attacker can gain access to information within the internal network, such as accessible addresses and ports, HTML page titles, and meta descriptions. Additionally, this vulnerability can be utilized for Denial-of-Service (DoS) attacks, allowing the attacker to request the server to download large files or chain several Server Side Request Forgery (SSRF) requests in a single attack.
