Name of the Vulnerable Software and Affected Versions Wikibase Wikidata Query Service GUI versions prior to 0.3.6-SNAPSHOT 2019-11-07

Description The issue allows for arbitrary JavaScript execution, which can occur when mathematical expressions in results are displayed directly. This can lead to XSS. The problem was addressed by introducing MathJax as a new mathematics rendering engine.

Recommendations For versions prior to 0.3.6-SNAPSHOT 2019-11-07, update to a version that includes the new mathematics rendering engine, such as 0.3.6-SNAPSHOT or later, to prevent arbitrary JavaScript execution.
