- Summary
- Coder's workspace app upsert allows cross-workspace agent rebinding via user-controlled app ID
- Details
-
Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2,
UpsertWorkspaceAppoverwrites an existing app'sagent_idon a primary-key conflict andinsertAgentAppaccepts the app ID from the provisioner'sCompleteJobpayload without verifying it belongs to the workspace being built.CompleteJobruns underdbauthz.AsProvisionerdso the authorization layer does not block the cross-workspace upsert. Exploitation requires elevated access as a template author or external provisioner operator. The fix in versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 verifies that any existingworkspace_appsrow matching the supplied ID belongs to the workspace being built and rejects cross-workspace agent reassignment. No known workarounds are available. - Database specific
