CVE-2021-21297: Improperly Controlled Modification of Dynamically-Determined Object Attributes

February 26, 2021 (updated September 22, 2021)

Node-Red is a low-code programming for event-driven applications built using nodejs. Node-RED 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 release. A workaround is to ensure only authorized users are able to access the editor url.
