CVE-2026-19723Network attack vector

Reflected XSS via unescaped inline event handler

Published Sep 2, 2026 · Updated Sep 2, 2026

Reflected XSS in Inisev Social Media Share Buttons & Social Sharing Icons before 3.0.1 allows remote attackers to execute script. The share-button rendering path inserts a request-derived value into an inline JavaScript event handler without context-appropriate escaping. A site must use a non-default icon display configuration, and a visitor must interact with the affected button; successful exploitation runs attacker-controlled script in that visitor's browser.
