NVD description

n8n versions before 2.39.6 and 2.40.0 before 2.40.1 contain an unescaped parameter interpolation vulnerability in SendGrid, Freshservice, and ServiceNow nodes that allows attackers to bypass filters by breaking out of query literals. Attackers can exploit this by binding vulnerable node parameters to untrusted external input to widen single-record lookups into match-all queries, exposing bulk data including contact lists, tickets, and directory entries.
