Summary

Coder: Devcontainer recreate endpoint missing write authorization allows read-only roles to destroy containers

Details

Summary

The devcontainer recreate endpoint relied on route middleware that checked only ActionRead on the workspace and, unlike the sibling delete endpoint, performed no ActionUpdate check before triggering the destructive rebuild.

Note: Exploitation requires an existing low-privilege role with access to the target workspace.

Impact

Any authenticated principal with read-only workspace access, such as a Template Admin or Org Template Admin, could recreate a devcontainer, destroying uncommitted in-container state and, if called repeatedly, denying service. This is an authorization bypass leading to data loss and denial of service.

Patches

The fix adds an explicit ActionUpdate authorization check before the agent is dialed like the delete endpoint.

The fix was backported to all supported release lines:

Release line	Patched version
2.34	v2.34.2
2.33	v2.33.8
2.32	v2.32.7
2.29 (ESR)	v2.29.17

Workarounds

None.
