CVE-2026-66572Network attack vector

Contributor-level stored cross-site scripting

Published Sep 17, 2026 · Updated Sep 19, 2026

Stored cross-site scripting in Crocoblock JetBlog 2.4.10 and earlier allows remote authenticated users to execute scripts in visitors' browsers. The CNA identifies CAPEC-592 Stored XSS but does not disclose the affected field, request route, rendering function, or missing sanitization or encoding operation. Contributor access is required, and exploitation depends on a privileged user or visitor loading the attacker-influenced content, enabling script execution in that viewer's session.
