CVE-2026-52888Public exploitNetwork attack vector

Password-hash disclosure via incomplete SQL blacklist

Published Jul 15, 2026 · Updated Jul 15, 2026

Sensitive data exposure in NocoBase before 2.0.62 allows remote authenticated users with the admin role to read password hashes. The checkSQL() blacklist omits PostgreSQL catalogs and application credential tables, letting direct SELECT queries return hashes, roles, active queries, and schema metadata without changing data. Admin access to SQL Collection is required; affected 2.1.0 alpha and beta builds expose the same data.
