CVE-2018-8046

• Exploited in the wild: not listed in CISA KEV
• EPSS: 66.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2018-07-05 · updated 2026-06-17
• Weakness: CWE-79

Description

The getTip() method of Action Columns of Sencha Ext JS 4 to 6 before 6.6.0 is vulnerable to XSS attacks, even when passed HTML-escaped data. This framework brings no built-in XSS protection, so the developer has to ensure that data is correctly sanitized. However, the getTip() method of Action Columns takes HTML-escaped data and un-escapes it. If the tooltip contains user-controlled data, an attacker could exploit this to create a cross-site scripting attack, even when developers took precautions and escaped data.

Affected products

• Sencha Ext Js: from 4.0.0 before 6.6.0 — fixed in 6.6.0

How to fix

Upgrade to a fixed version: Sencha Ext Js 6.6.0. Check the vendor advisory for mitigations.
