MEDIUM 4.6EPSS 0.20%

Does this matter?

Lower severity and a low EPSS score (0.20%). Track it; it rarely justifies an emergency change on its own.

Description

An authenticated attacker can store a crafted tag value in _user_tags and trigger JavaScript execution when a victim opens the list/report view where tags are rendered. The vulnerable renderer interpolates tag content into HTML attributes and element content without escaping. This issue affects Frappe: 16.10.10.
