Hi,

The following vulnerability was published for node-prismjs.

CVE-2020-15138[0]:
| Prism is vulnerable to Cross-Site Scripting. The easing preview of the
| Previewers plugin has an XSS vulnerability that allows attackers to
| execute arbitrary code in Safari and Internet Explorer. This impacts
| all Safari and Internet Explorer users of Prism >=v1.1.0 that use
| the _Previewers_ plugin (>=v1.10.0) or the _Previewer: Easing_
| plugin (v1.1.0 to v1.9.0). This problem is fixed in version 1.21.0. To
| workaround the issue without upgrading, disable the easing preview on
| all impacted code blocks. You need Prism v1.10.0 or newer to apply
| this workaround.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
