Description

Frappe before 13.46.1 and 14.x before 14.20.0 contains a cross-site scripting vulnerability because the html2text function weakly sanitizes user input. Authenticated attackers can supply crafted HTML that is insufficiently sanitized by html2text, executing scripts in the browsers of users who view the rendered content.

Affected products

frappe: before 13.46.1; from 14.0.0-beta.1 before 14.20.0 — fixed in 13.46.1, 14.20.0

How to fix

Upgrade to a fixed version: frappe 13.46.1, 14.20.0. Check the vendor advisory for mitigations.
