Vulnerability Title
NocoBase: Sensitive Data Exposure via SQL Blacklist Bypass
Source: CVE Program / CVE List V5
Vulnerability Description
NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. In 2.0.59 and earlier, NocoBase @nocobase/plugin-collection-sql used the checkSQL() function in packages/plugins/@nocobase/plugin-collection-sql/src/server/utils.ts with an incomplete keyword blacklist that did not restrict PostgreSQL system catalog tables such as pg_shadow, pg_roles, and pg_stat_activity, allowing an admin-role user to read password hashes and database metadata through the SQL Collection feature. This vulnerability is fixed in 2.1.0-alpha.46.
