    "lastseen": "",
    "description": "n8n is an open source workflow automation platform. Prior to versions 1.118.0 and 2.4.0, a vulnerability in the Merge node's SQL Query mode allowed authenticated users with permission to create or modify workflows to write arbitrary files to the n8n server's filesystem potentially leading to remote code execution. This issue has been patched in versions 1.118.0 and 2.4.0.",
