Summary

Network-AI is a TypeScript/Node.js multi-agent orchestrator. Prior to version 5.12.2, `EnvironmentManager.restore(env, backupId)` computes the backup path with `join(envDir, '.backups', backupId)` and only checks that this path exists. It does not resolve the result or verify that it remains under `data/<env>/.backups`. A caller can pass a traversal backup ID such as `../../../outside/source-dir` to restore files from an arbitrary directory into the target environment data directory. The issue is fixed in v5.12.2. `restore()` now validates `backupId` against `/^[\w\-]+$/` and asserts `dirname(resolve(join(backupsDir, backupId))) === resolve(backupsDir)` before touching the filesystem. Backup IDs containing path separators or `..` are rejected, so a crafted ID can no longer copy directories from outside `.backups/` into the environment.
