This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Version 1.8.1 contains a patch for this issue.
.This CVE has a CVSS3.1 score of 6.3 and a Base Severity of MEDIUM.
