Vulnerability Title
NocoBase Vulnerable to SQL Injection via String Concatenation in Recursive Eager Loading
Source: NVD (National Vulnerability Database)
Vulnerability Description
NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to version 2.0.39, the queryParentSQL() function in the core database package constructs a recursive CTE query by joining nodeIds with string concatenation instead of using parameterized queries. The nodeIds array contains primary key values read from database rows. An attacker who can create a record with a malicious string primary key can inject arbitrary SQL when any subsequent request triggers recursive eager loading on that collection. This issue has been patched in version 2.0.39.

| # | POC Description | Source Link | Shenlong Link |
|---|---|---|---|
| 1 | NocoBase versions prior to 2.0.39 contain a SQL injection vulnerability in the @nocobase/database package. The queryParentSQL function in eager-loading-tree.ts constructs a recursive CTE query by directly concatenating user-controlled primary key values into the SQL WHERE IN clause without parameterization. An authenticated attacker with record creation permissions on a tree collection with string-type primary keys can inject arbitrary SQL via crafted record identifiers, enabling full database compromise including data exfiltration and modification. | https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-41640.yaml | POC Details |
