NVD Description

Note: Versions mentioned in the description apply only to the upstream grafana12.4 package and not the grafana12.4 package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

DOMPurify before 3.4.17 contains a cross-site scripting vulnerability that allows attackers to bypass the SMIL attributeName=href guard when PARSER_MEDIA_TYPE is application/xhtml+xml, because transformCaseFunc does not lowercase attribute names. Attackers can submit SVG with an animate or set element using attributeName="href" and a javascript: entry in values to execute script when users click the sanitized link.
