DescriptionCVE.org

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, 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. Exploitation requires an existing low-privilege role with access to the target workspace. The fix in versions 2.29.7, 2.32.7, 2.33.8, and 2.34.2 adds an explicit `ActionUpdate` authorization check before the agent is dialed like the delete endpoint. No known workarounds are available.
