CVE-2022-46181 – Gotify server XSS vulnerability in the application image file upload

https://notcve.org/view.php?id=CVE-2022-46181

Gotify server is a simple server for sending and receiving messages in real-time per WebSocket. Versions prior to 2.2.2 contain an XSS vulnerability that allows authenticated users to upload .html files. An attacker could execute client side scripts **if** another user opened a link. The attacker could potentially take over the account of the user that clicked the link. The Gotify UI won't natively expose such a malicious link, so an attacker has to get the user to open the malicious link in a context outside of Gotify. • https://github.com/gotify/server/pull/534 https://github.com/gotify/server/pull/535 https://github.com/gotify/server/security/advisories/GHSA-xv6x-456v-24xh • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
