OpsTree BuildPiper before 2.7.0 contains a path traversal vulnerability that allows authenticated users to read arbitrary files by supplying traversal sequences in Additional Manifest file paths. Attackers can enter paths like ../../../../etc/passwd so the renderer embeds file contents in generated manifests and logs, exposing configuration files and service-account tokens.
