Description
Coder allows organizations to provision remote development environments via Terraform. Prior to versions 2.29.7 and 2.30.2, workspace creation via `mode=auto` deep links silently provisioned workspaces with attacker-controlled parameters, requiring no explicit user confirmation. In versions 2.29.7 and 2.30.2, a consent dialog was added that displays all prefilled `param.*` values and blocks creation until the user explicitly clicks Confirm and Create.
