CVE-2021-21297

Node-Red is a low-code programming for event-driven applications built using nodejs. Node-RED 1.2.7 and earlier contains a Prototype Pollution vulnerability in the admin API. A badly formed request can modify the prototype of the default JavaScript Object with the potential to affect the default behaviour of the Node-RED runtime. The vulnerability is patched in the 1.2.8 release. A workaround is to ensure only authorized users are able to access the editor url.
