Title: NocoBase Vulnerable to SQL Validation Bypass via `sqlCollection:update` Missing `checkSQL` Call (CVE-2026-41641)
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 checkSQL() validation function that blocks dangerous SQL keywords (e.g., pg_read_file, LOAD_FILE, dblink) is applied on the collections:create and sqlCollection:execute endpoints but is entirely missing on the sqlCollection:update endpoint. An attacker with collection management permissions can create a SQL collection with benign SQL, then update it with arbitrary SQL that bypasses all validation, and query the collection to execute the injected SQL and exfiltrate data. This issue has been patched in version 2.0.39.

Description

NocoBase @nocobase/plugin-collection-sql versions prior to 2.0.39 are vulnerable to SQL injection via the sqlCollection:update endpoint. The checkSQL() function, which blocks dangerous SQL keywords and ensures only SELECT statements are allowed, is not called during collection updates.
