CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Professional Social Sharing Buttons, Icons & Related Posts < 7.6.1.0 takes an account at Subscriber level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Professional Social Sharing Buttons, Icons & Related Posts the fix is 7.6.1.0: builds < 7.6.1.0 are affected, anything from 7.6.1.0 onward is not.
Remediation
Update to version 7.6.1.0, or a newer patched version
How does WordSec protect against this?
An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Professional Social Sharing Buttons, Icons & Related Posts 7.6.1.0 closes this, and updating the plugin is the step that ends it.
