Vulnerability Description
IBM Carbon Charts 0.4.0 through 1.27.19 is vulnerable to cross-site scripting. The MeterChart component's Title.truncateTitle() function re-inserts a substring of user-supplied label text into the DOM via an unsanitized innerHTML write when the title exceeds the available container width.
