CyberRota Analysis

AI-Generated

The SQL injection vulnerability affects n8n versions prior to 1.123.80 and from 2.0.0 before 2.39.6, as well as from 2.40.0 before 2.40.1, specifically within the Oracle Database node's Delete Table Drop operation. This flaw allows attackers to manipulate SQL statements by injecting single quotes into table or schema fields, potentially executing unauthorized DDL or DML commands with the privileges of the connected database credentials. Organizations using affected n8n versions, particularly those integrating with Oracle databases, should prioritize patching to mitigate the risk of data breaches and unauthorized access.
