Q: How do I fix it?

Update Social Media Share Buttons & Social Sharing Icons to version 3.0.1 or later. That is the complete fix. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

CVE-2026-19723

Vulnerability CVE-2026-19723 PLUGIN social-media-share-buttons-social-sharing-icons HIGH

The Social Media Share Buttons & Social Sharing Icons WordPress plugin before 3.0.1 does not properly escape a value taken from the incoming request before outputting it in an inline JavaScript event handler, leading to Reflected Cross-Site Scripting which is triggered when a user interacts with the affected button. Exploitation requires the Social Media Share Buttons & Social Sharing Icons WordPress plugin before 3.0.1 to be running a non-default icon display configuration.
