Description
OpsTree BuildPiper before 2.7.0 contains an authorization bypass vulnerability that allows authenticated users to link pipeline stages to environments of other projects by supplying a foreign project_env_id. Attackers can submit another project's environment identifier to the POST /api/v1/pipeline/{pipeline_id}/stages/ endpoint, persisting cross-project associations that bypass project separation.
