CVE-2025-65590Network attack vector

Stored script execution via unneutralized blog overview

Published Dec 16, 2025 · Updated Dec 16, 2025

Stored XSS in nopCommerce 4.90.0 allows remote authenticated users to execute scripts in visitors' browsers through crafted blog posts. The Content Management blog editor stores HTML or JavaScript entered in the Body overview field and renders it on the public blog page without neutralization. A user with blog-management privileges must save the payload, and another user must visit the affected page; the nopCommerce team disputes that a store owner crosses a security boundary.
