The Google Web Toolkit (GWT) framework exchanges data using JavaScript Object Notation (JSON) without an associated protection scheme, which allows remote attackers to obtain the data via a web page that retrieves the data through a URL in the SRC attribute of a SCRIPT element and captures the data using other JavaScript code, aka "JavaScript Hijacking."

Unspecified vulnerability in the benchmark reporting system in Google Web Toolkit (GWT) before 1.4.61 has unknown impact and attack vectors, possibly related to cross-site scripting (XSS).

GWT: unknown XSS flaw

Cross-site scripting (XSS) vulnerability in Google Web Toolkit (GWT) 2.4 through 2.5 Final, as used in JBoss Operations Network (ON) 3.1.1 and possibly other products, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
