By staying informed and taking proactive steps, organizations can protect themselves against potential threats and maintain the integrity of their systems and data.

Technical summary

ToolJet before v3.16.208 fails to validate organization membership in database read routes, allowing any authenticated user to access other organizations' table schemas and row data. Attackers can supply arbitrary organization IDs in URL parameters to list tables, retrieve column definitions, and execute join queries to read actual stored data from victim organizations. This vulnerability is considered high severity and requires immediate attention from administrators responsible for database security.

Defensive priority

Organizations using ToolJet should prioritize patching to prevent unauthorized data access.

Recommended defensive actions

• Apply patches for ToolJet v3.16.208 or later
• Restrict access to database read routes
• Monitor for suspicious database queries
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
