Description

XML Injection vulnerability in xmltodict allows Input Data Manipulation. This issue affects xmltodict: from 0.14.2 before 0.15.1. NOTE: the scope of this CVE is disputed by the vendor on the grounds that xmltodict.unparse() delegates element-name handling to Python's xml.sax.saxutils.XMLGenerator, and that XMLGenerator should be the component performing validation.

Affected products

• xmltodict: from 0.14.2 before 0.15.1 — fixed in 0.15.1

How to fix

Upgrade to a fixed version: xmltodict 0.15.1. Check the vendor advisory for mitigations.
