NVD description

n8n before 1.123.85, 2.x before 2.43.5, and 2.44.x before 2.44.1 contains a filter injection vulnerability in the Quick Base node, which sends the Where filter to the Quick Base API as raw query text. Attackers supplying untrusted input such as webhook data used to build the filter can make Get Many return every record or Delete remove every record with the workflow credential's privileges.

What to do

  • Do not expose the component's API or UI to the internet without authentication in front of it.
