Description

This security bulletin contains information about 1 vulnerability.


1) SQL injection (CVE-ID: N/A)

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to execute arbitrary SQL queries in database.

The vulnerability exists due to insufficient sanitization of user-supplied data. A remote user with permission to create or modify workflows and access to a database credential can unknowingly create a workflow that was vulnerable to SQL injection, even while expecting inputs to be handled safely through escaped parameters.
