What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

SemanticMediaWiki from 5.0.0 before 7.3.1 contains a stored cross-site scripting vulnerability in ext.smw.tooltip.tippy.js that renders data-* attributes via innerHTML with allowHTML enabled. Editors can plant a .smw-highlighter span with a malicious data-content, data-title, data-top, data-bottom, or data-theme attribute to execute JavaScript when viewers, including administrators, hover it.
