overture

The tool's core functionality involves reading and writing configuration files (JSON, YAML) and executing arbitrary commands based on its configuration. While this is justified by its purpose as a configuration orchestrator, internal code reviews highlight specific security concerns: (1) Potential path traversal vulnerability in backup filename generation, where an unsanitized filename could be crafted to overwrite arbitrary files. (2) Direct environment variable expansion using `process.env[varName]` without robust sanitization or an allowlist, which could lead to information disclosure or command influence if a malicious configuration specifies variable names an attacker controls. (3) Reliance on external binaries (`claude`, `npm`, `uvx`, `docker`) whose execution is delegated but also driven by the configuration, making the overall security dependent on the integrity of the Overture configuration file and the invoked external tools. The `execSync` is mostly confined to test environments, but `execa` is used for external process execution, which generally handles arguments more safely, but the `command` itself in configurations could still be a vector.
