DOMPurify from 3.4.13 before 3.4.16 DOM XSS via IN_PLACE afterSanitize Hooks
DOMPurify from 3.4.13 before 3.4.16 contains a cross-site scripting vulnerability because IN_PLACE mode fails to neutralize subtrees detached by afterSanitizeElements or afterSanitizeAttributes hooks. Attackers can supply markup with on* handlers inside a wrapper removed by such hooks, leaving handlers armed on the live DOM to execute script in the victim origin.
