Stored XSS in Search in usememos/memos


Reported on

Dec 21st 2022


Stored XSS is a type of XSS that stores malicious code on the application. The demo website is affected of it.

Proof of Concept

#1. Access to the demo website

#2. At "Any thoughts....", write XSS Payload and save it. In this scenario, I used payload: "><img src=x onerror=alert("XSS")>

#3. Now, at Search bar, just type "> (or any character in the payload) and the payload will be triggered.
