The MonsterInsights Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via an unknown parameter in versions up to, and including, 8.14.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

CVSS

Score:6.5

Severity:Medium

Version: 8.14.1

There is a patch available in v8.15 and we strongly recommend you update to this version as soon as possible.
