CVE-2019-15607Public exploitNetwork attack vector

Stored script execution via unsanitized flow names

Published Jan 28, 2020 · Updated Aug 5, 2024

Stored XSS in Node-RED 0.20.7 and earlier allows remote authenticated users to execute JavaScript in another editor user's browser. The editor fails to sanitize a new Flow's name field before rendering it, so a persisted HTML or script payload executes when another user views the flow. The attacker needs flow-write access and a victim must open the affected editor content; execution can expose session cookies or alter displayed content.
