OpenClaude is an open-source coding-agent command line interface for cloud and local model providers. Versions prior to 0.5.1 have a logic flaw in "bashToolHasPermission()" inside "src/tools/BashTool/bashPermissions.ts". When the sandbox auto-allow feature is active and no explicit deny rule is configured, the function returns an "allow" result immediately — before the path constraint filter ("checkPathConstraints") is ever evaluated. This allows commands containing path traversal sequences (e.g., "../../../../../etc/passwd") to bypass directory restrictions entirely. Version 0.5.1 contains a patch for the issue.
