How to fix?

There is no fixed version for RHEL:7 openshift4/ose-monitoring-plugin-rhel9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift4/ose-monitoring-plugin-rhel9 package and not the openshift4/ose-monitoring-plugin-rhel9 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

DOMPurify 3.0.0 before 3.4.9 does not reset the retained Trusted Types policy when clearConfig() is called, so a DOMPurify instance reused across trust boundaries stays bound to a previously supplied TRUSTED_TYPES_POLICY. A later caller that requests RETURN_TRUSTED_TYPE output receives a TrustedHTML object created by the old (potentially unsafe) policy rather than a clean default, which can lead to script execution at a Trusted Types sink. Passing TRUSTED_TYPES_POLICY: null on the later call also does not clear the retained policy.
