Technical Analysis
CVE-2026-82239 is a missing authorization vulnerability in Budibase server prior to version 3.41.3. The issue occurs because the server fails to enforce per-table role restrictions on the POST /api/datasources/query endpoint. As a result, attackers with BASIC role privileges can bypass table-level access controls by submitting crafted queries with target table identifiers, allowing them to read, create, update, or delete rows in any table regardless of configured permissions.
Potential Impact
Attackers with BASIC role privileges can bypass intended access controls to read and manipulate data in any table, potentially leading to unauthorized data disclosure, modification, or deletion. This compromises data integrity and confidentiality within affected Budibase server deployments.
Mitigation Recommendations
A fix is available in Budibase server version 3.41.3. Users should upgrade to version 3.41.3 or later to remediate this vulnerability. No additional vendor advisory content is provided; therefore, patching to the fixed version is the recommended mitigation.
