Technical details

The vulnerability is a stored XSS in Apache Roller's authoring UI caused by user-controlled values embedded directly into inline JavaScript string literals and written to the page via jQuery's .html() method without proper encoding. An authenticated author can craft malicious content that breaks out of JavaScript literals and executes arbitrary code in another author's or administrator's session. The fix in version 6.1.6 moves these values out of JavaScript literals into HTML data attributes and uses text APIs instead of .html() for rendering.

Affected products

Apache Roller 6.1.5 and earlier
