Note: Versions mentioned in the description apply only to the upstream wazuh-dashboard package and not the wazuh-dashboard package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

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.
