CVE-2026-65913 · DOMPurify before 3.3.2 Prototype Pollution via USE_PROFILES
This page contains facts from public vulnerability sources. Check the original advisory before updating.
DOMPurify before 3.3.2 contains a prototype pollution vulnerability in USE_PROFILES mode that allows attackers to bypass attribute filtering by polluting Array.prototype properties. Attackers can set Array.prototype properties like onclick to true, causing DOMPurify to accept event handlers as allowlisted attributes and resulting in DOM-based XSS when sanitized markup is rendered.
