CVE-2023-43233Network attack vector

Arbitrary browser script execution via stored titles

Published Sep 27, 2023 · Updated Sep 24, 2024

Stored XSS in YZNCMS 1.3.0 allows remote attackers to execute arbitrary scripts or HTML through the cms/content/edit title parameter. The component stores a crafted title value and later renders it without adequate neutralization, causing script execution in a viewer's browser. No authentication is required to submit the payload, but exploitation requires another user to view the affected content and can expose or alter data available to that browser context.
