CVE-2026-42653Known exploitationNetwork attack vector

Unauthenticated stored script execution in visitor browsers

Published Jun 11, 2026 · Updated Jun 11, 2026

Stored XSS in SliceWP 1.2.6 and earlier allows remote attackers to inject scripts that execute when affected WordPress pages are viewed. Patchstack and the CNA record do not identify the input field, request handler, or output routine that stores and renders the unneutralized input. Exploitation is unauthenticated but requires another user to view the affected content, enabling browser-context data access and actions under that user's session.
