Severity: critical

Cross-Site Scripting



Affected versions of swagger-ui are vulnerable to cross-site scripting in both the consumes and produces parameters of the swagger JSON document for a given API.

Additionally, swagger-ui allows users to load arbitrary swagger JSON documents via the query string parameter url, allowing an attacker to exploit this attack against any user that the attacker can convince to visit a crafted link.

Proof of Concept



Update to version 2.2.1 or later.
