CVE-2026-80049: Authorization Bypass Through User-Controlled Key in airbytehq airbyte-platform
Description
CVE-2026-80049 is an authorization bypass vulnerability in airbytehq's airbyte-platform affecting versions up to and including 2.0.0. The platform uses a workspace identifier supplied by the caller to make authorization decisions, but does not verify that the resource being accessed actually belongs to the authorized workspace. This allows any member of a workspace to access or modify resources in other workspaces at their own privilege level.

Technical Analysis
The airbyte-platform resolves the workspace for authorization from a user-supplied field in the request body, which is copied into headers and used for permission checks. However, the platform does not verify that the resource's owning workspace matches the authorized workspace. As a result, a user can specify a workspace ID they belong to but operate on resources belonging to other workspaces, enabling unauthorized read, trigger, cancel, and delete actions on connections, sources, and destinations across workspaces.
Potential Impact
An attacker who is a member of any workspace can bypass authorization controls to access and manipulate resources belonging to other workspaces. This includes reading configurations, triggering or canceling syncs, and deleting connections, sources, and destinations. The vulnerability allows privilege escalation within the platform limited by the attacker's own workspace privileges but affecting resources outside their authorized scope.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to trusted users and monitor for suspicious activity related to workspace resource access. Avoid relying on user-supplied workspace identifiers for authorization decisions.
