CVE-2026-103253: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in n8n-io n8n
n8n versions before 1.123.80, from 2.0.0 before 2.39.6, and from 2.40.0 before 2.40.1 contain an SQL injection vulnerability in the Oracle Database node's Delete Table Drop operation. Attackers can inject single quotes in the table or schema fields to append arbitrary SQL statements and execute DDL or DML commands against the connected database with the credential's privileges.
AI Analysis
Technical Summary
CVE-2026-103253 is an SQL injection vulnerability affecting the n8n automation platform in specific versions. The vulnerability arises from improper neutralization of special elements in SQL commands within the Oracle Database node's Delete Table Drop operation. Attackers can exploit this by injecting single quotes into the table or schema input fields, enabling them to append and execute arbitrary DDL or DML SQL statements against the connected Oracle database using the credentials' privileges.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary SQL commands on the connected Oracle database with the privileges of the database credentials used by n8n. This can lead to unauthorized data manipulation, schema changes, or other database operations, potentially compromising data integrity and confidentiality.
Mitigation Recommendations
A fix is available in n8n versions 1.123.80 and later, 2.39.6 and later, and 2.40.1 and later. Users should upgrade to these versions to remediate the vulnerability. No additional mitigation steps are indicated.
