Summary
RSSHub is vulnerable to Server-Side Request Forgery (SSRF) attacks. This vulnerability allows an attacker to send arbitrary HTTP requests from the server to other servers or resources on the network.
Description
An attacker can exploit this vulnerability by sending a request to the affected routes with a malicious URL. For example, if an attacker controls the ATTACKER.HOST domain, they can send a request to affected routes with the value set to ATTACKER.HOST%2F%23.
The %2F and %23 characters are URL-encoded versions of the forward-slash (/) and pound (#) characters, respectively. In this context, an attacker could use those characters to append the base URL (i.e. https://${input}.defined.host) to be modified to https://ATTACKER.HOST/#.defined.host. This will cause the server to send a request to the attacker-controlled domain, allowing the attacker to potentially gain access to sensitive information or perform further attacks on the server.
Impact
An attacker could use this vulnerability to send requests to internal or any other servers or resources on the network, potentially gain access to sensitive information that would not normally be accessible and amplifying the impact of the attack.

The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. The attacker needs the user to perform some action, like clicking a link. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a low impact on the integrity of the data. There is a low impact on the availability of the system.
Exploitation activity has been observed. Apply available patches or mitigations urgently.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
