CVE-2026-100685: Incorrect Authorization in budibase server
Budibase before 3.45.0 fails to properly scope the GET /api/chat-links endpoint by workspace, allowing builders to enumerate chat identity link records across all workspaces in a tenant. Attackers with builder access to a single workspace can retrieve sensitive chat identity linking data including user IDs and external chat service identifiers from other workspaces they have no permission to access.
AI Analysis
Technical Summary
Budibase server versions prior to 3.45.0 do not properly enforce workspace scoping on the GET /api/chat-links API endpoint. This authorization flaw enables users with builder privileges in a single workspace to access chat identity linking data from other workspaces in the tenant, violating data isolation boundaries. The vulnerability has a CVSS 4.0 score of 8.3, indicating high severity due to network attack vector, low attack complexity, and high impact on confidentiality.
Potential Impact
Attackers with builder access to any single workspace can retrieve sensitive chat identity linking information, including user IDs and external chat service identifiers, from other workspaces they are not authorized to access. This can lead to unauthorized disclosure of sensitive user data across workspace boundaries within the same tenant.
Mitigation Recommendations
A fix is available in Budibase server version 3.45.0. Users should upgrade to version 3.45.0 or later to remediate this authorization vulnerability. No additional mitigation steps are indicated.
