Security Bulletin
Summary
Carbon Charts has updated its DOMPurify dependency from 3.4.0 to 3.4.12, resolving 9 CVEs identified by security scanning (CVE-2026-49978 Critical CVSS 9.3, CVE-2026-65898 High CVSS 7.2, CVE-2026-66010 Medium CVSS 6.1, CVE-2026-65902 Medium CVSS 6.1, CVE-2026-65901 Medium CVSS 6.1, CVE-2026-65900 Medium CVSS 6.1, CVE-2026-65899 Medium CVSS 6.1, CVE-2026-49459 Medium CVSS 6.1, CVE-2026-49458 Medium CVSS 6.1). All vulnerabilities affect the sanitize() API used internally by Carbon Charts to sanitize user-supplied HTML in chart labels, tooltips, and similar fields. Who is affected: Any application using @carbon/charts or its framework wrappers (@carbon/charts-react, @carbon/charts-angular, @carbon/charts-vue, @carbon/charts-svelte) that passes untrusted user-generated content into chart data fields. Action required: Update to the latest patch release of @carbon/charts and all framework packages.
Vulnerability Details
CVEID: CVE-2026-49458
DESCRIPTION: DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.6, DOMPurify.sanitize(node, { IN_PLACE: true }) accepted same-origin foreign-realm DOM nodes while follow-on checks used parent-realm constructors, causing instanceof checks for forms, named node maps, document fragments, and elements to fail and skip clobber, template-content, and shadow-DOM sanitization branches so executable markup could survive. This issue is fixed in version 3.4.6.
CWE: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVEID: CVE-2026-49459
DESCRIPTION: DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.6, DOMPurify.sanitize(root, { IN_PLACE: true }) could preserve event-handler attributes on an attacker-controlled form root when a descendant name clobbered properties checked by _isClobbered, because _forceRemove no-opped on the parent-less root and _sanitizeAttributes returned early. This issue is fixed in version 3.4.6.

CVEID: CVE-2026-49978
DESCRIPTION: DOMPurify is a DOM-only cross-site scripting sanitizer for HTML, MathML, and SVG. Prior to 3.4.7, DOMPurify IN_PLACE sanitization could skip shadow contents attached to an element inside template.content, allowing attacker-controlled markup such as event handlers, JavaScript URLs, or scripts to survive and execute when an application cloned and inserted the sanitized template. This issue is fixed in version 3.4.7.

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
