Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-79.

Summary

The WP PageNavi Style WordPress plugin through 1.4 does not sanitise or escape some of its settings, which allows cross-site scripting (CWE-79). It also has no CSRF check when those settings are saved, so an attacker can make a logged-in administrator store arbitrary JavaScript that runs in the browser of every visitor to the site's front end. A public exploit is linked in the references.
