OS Command Injection in @nocobase/plugin-backups (CVE-2026-55410)
Summary
OS command injection in @nocobase/plugin-backups (CVE-2026-55410). Data can be tampered with by attackers. Exploitable via database.schema. Mitigation: upgrade to 2.1.19 or later.
Original description
The description as published by the source.
NocoBase is an AI-powered no-code/low-code platform for building business applications and enterprise solutions. Prior to 2.1.19, NocoBase @nocobase/plugin-backups restored PostgreSQL backups by interpolating the database.schema value from _metadata.json into shell command strings executed with Node.js child_process.exec(), allowing a backup-management user restoring a crafted backup to execute commands as the NocoBase server process. This vulnerability is fixed in 2.1.19.
