How to fix?

Upgrade github.com/usememos/memos/api/v1 to version 0.16.1 or higher.

Overview

github.com/usememos/memos/api/v1 is a lightweight note-taking service

Affected versions of this package are vulnerable to Server-Side Request Forgery (SSRF) due to an improper check of user-supplied URLs in the /o/get/image endpoint. An attacker can enumerate the internal network and retrieve images by sending crafted requests to this endpoint. The maliciously retrieved image's response is then included in the server's response to the attacker, leading to a reflected cross-site scripting (XSS) issue.
