Executive Summary

The vulnerability in Teable's v2 REST API controller is due to missing @Permissions metadata on ORPC endpoints. This absence causes a lack of authorization checks, allowing any authenticated user to bypass these controls.

As a result, attackers can perform unauthorized actions such as reading table schemas, creating new tables, and modifying or deleting records across different bases and tables using endpoints like GET /api/v2/tables/get and POST /api/v2/tables/updateRecords.

Mitigation Strategies

To mitigate the CVE-2026-56773 vulnerability in Teable's v2 REST API, you should upgrade to the fixed version released after 2026-06-15T04-43-24Z.1912, as this release addresses the missing authorization checks.

Since the vulnerability allows any authenticated user to bypass authorization checks, restricting access to the API endpoints to trusted users only and monitoring API usage for suspicious activity can also help reduce risk until the patch is applied.
