Memos 0.22 is vulnerable to Stored Cross site scripting (XSS) vulnerabilities by the upload attachment and user avatar f

Memos 0.22 is vulnerable to Stored Cross site scripting (XSS) vulnerabilities by the upload attachment and user avatar features. Memos does not verify the content type of the uploaded data and serve it back as is. An authenticated attacker can use this to elevate their privileges when the stored XSS is viewed by an admin.
