    Improper Initialization

    org.webjars.npm:dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG.

    Affected versions of this package are vulnerable to Improper Initialization in the DOMPurify.setConfig() API when an uponSanitizeAttribute hook is registered that mutates allowedAttributes. An attacker can cause persistent modification of the attribute allowlist by submitting specially crafted content, resulting in unauthorized attributes being permitted in all subsequent sanitization calls.

    How to fix Improper Initialization?

    Upgrade org.webjars.npm:dompurify to version 3.4.11 or higher.

    Protection Mechanism Failure

    org.webjars.npm:dompurify is a DOM-only XSS sanitizer for HTML, MathML and SVG.

    Affected versions of this package are vulnerable to Protection Mechanism Failure through the clearConfig function. An attacker can execute arbitrary scripts in a Trusted Types sink by influencing a previously supplied TRUSTED_TYPES_POLICY on a reused instance and later triggering output with RETURN_TRUSTED_TYPE: true.

    Note:

    This is only exploitable if a DOMPurify instance is reused across trust boundaries and a less-trusted integration or attacker has previously set an unsafe Trusted Types policy.

    How to fix Protection Mechanism Failure?

    Upgrade org.webjars.npm:dompurify to version 3.4.9 or higher.
