Upgrade to BuildPiper version 2.7.0 or later, where this authorization bypass vulnerability has been fixed. No other mitigation actions are indicated by the vendor advisory.
Description
OpsTree BuildPiper versions before 2.7.0 have an authorization bypass vulnerability that allows authenticated users to misuse another application's environment by supplying a foreign project_env_id. This enables attackers to configure continuous integration (CI) and trigger builds and deployments using the other application's settings and infrastructure.
