CVE-2026-41640
HIGH NUCLEINocoBase Vulnerable to SQL Injection via String Concatenation in Recursive Eager Loading
Title source: cnaExploitation Summary
CVE-2026-41640 has a Nuclei detection template available — see the Nuclei card below for the Shodan/FOFA recon queries.
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.
