AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the n8n workflow automation platform, specifically in the Merge node's SQL Query mode. Before versions 1.118.0 and 2.4.0, authenticated users who had permission to create or modify workflows could exploit this flaw to write arbitrary files to the server's filesystem. This could potentially allow an attacker to execute remote code on the server.
How can this vulnerability impact me? :
If exploited, this vulnerability could allow an attacker with certain permissions to write arbitrary files on the n8n server, which may lead to remote code execution. This means the attacker could potentially take control of the server, manipulate workflows, access sensitive data, or disrupt services.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
