n8n-nodes-base is vulnerable to Prototype Pollution
70
High Risk
Affected versions of this package are vulnerable to prototype pollution due to inadequate validation of object keys. Although forbidden keys are validated, this check can be bypassed with a nested object containing those keys. An attacker could exploit this by crafting a JSON payload that pollutes the prototype chain, allowing them to inject properties into all objects in the application, potentially leading to remote code execution or other security issues.
You are affected if you are using a version that falls within the vulnerable range.
n8n-nodes-base is vulnerable to Prototype Pollution in versions 1.55.0 - 1.94.1.
