Attack profile from CVSS 3.1 · CNA. Fix status from CNA. Impact type from CWE-639.
Summary
Plane, an open-source project management tool, is affected before 1.4.0. The BulkEstimatePointEndpoint.destroy function looks up an estimate point by primary key without workspace, project, or estimate scoping (CWE-639). An administrator or member of one workspace can permanently delete an estimate point belonging to another workspace by referencing its identifier under their own workspace.

Description from the CNA
Plane is an open-source project management tool. Prior to 1.4.0, BulkEstimatePointEndpoint.destroy resolves an estimate point through a bare primary-key lookup without workspace, project, or estimate scoping. An administrator or member of one workspace can permanently delete an estimate point belonging to another workspace by supplying the target UUID in a URL under the attacker's own workspace. This creates a destructive cross-tenant IDOR. This issue is fixed in 1.4.0.
