Description

Frappe ERPNext before 15.119.1 and 16.x before 16.32.0 contains a stored cross-site scripting vulnerability because content submitted through a public-facing booking page is stored without neutralization. Unauthenticated attackers can submit crafted content that is rendered as raw HTML in a privileged user's session, executing script to act as that user and take over the account.
