CVE-2026-41640: NocoBase Vulnerable to SQL Injection via String Concatenation in Recursive Eager Loading

Noroxi assessment

Priority: Monitor (action score 36/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 1.8% (FIRST EPSS); higher than 79.4% of all records.
Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: nocobase nocobase 2.0.39.

Low priority for now. Upgrade to nocobase nocobase 2.0.39 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
