CWE-918

Nextcloud mail is an email app for the nextcloud home server platform. In affected versions the SMTP, IMAP and Sieve host fields allowed to scan for internal services and servers reachable from within the local network of the Nextcloud Server. It is recommended that the Nextcloud Maill app is upgraded to 1.15.0 or 2.2.2. The only known workaround for this issue is to completely disable the nextcloud mail app.

Haven 5d15944 allows Server-Side Request Forgery (SSRF) via the feed[url]= Feeds functionality. Authenticated users with the ability to create new RSS Feeds or add RSS Feeds can supply an arbitrary hostname (or even the hostname of the Haven server itself). NOTE: this product has significant usage but does not have numbered releases; ordinary end users may typically use the master branch.

In certain Lexmark products through 2023-01-12, SSRF can occur because of a lack of input validation.

RSSHub is an open source RSS feed generator. 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. An attacker can exploit this vulnerability by sending a request to the affected routes with a malicious URL. An attacker could also 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 patch for this issue can be found in commit a66cbcf.
