Cross-Site Scripting in selectize-plugin-a11y

Versions of selectize-plugin-a11y prior to 1.1.0 are vulnerable to Cross-Site Scripting. The accessibility.liveRegion.speak function does not sanitize the msg variable before rendering it as HTML. If this variable is controlled by user input it allows attackers to execute arbitrary JavaScript in a victim’s browser.

Recommendation

Upgrade to version 1.1.0 or later.
