CVE-2026-52888 nocobase CVE debrief

Who should care

Users of NocoBase 2.0.59 and earlier should apply the patch in 2.1.0-alpha.46 to prevent potential unauthorized access to sensitive database information. This includes administrators, developers, and security teams responsible for managing and securing NocoBase deployments. Additionally, operators and platform teams should review the vulnerability and plan for updates or mitigations through normal change control where exposure is confirmed.

Technical summary

The @nocobase/plugin-collection-sql in NocoBase 2.0.59 and earlier contains a vulnerability due to an incomplete keyword blacklist in the checkSQL() function. This allows an admin-role user to access PostgreSQL system catalog tables such as pg_shadow, pg_roles, and pg_stat_activity, potentially leading to the exposure of password hashes and database metadata. The vulnerability is addressed in version 2.1.0-alpha.46. The CVSS score is 6.8, indicating a medium severity vulnerability.

Defensive priority

Medium priority due to the potential for sensitive information disclosure. Defenders should prioritize patching and restricting access to the SQL Collection feature.

Recommended defensive actions

• Apply the patch in 2.1.0-alpha.46 or later
• Restrict access to the SQL Collection feature for admin-role users
• Monitor for suspicious activity related to database metadata access
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
