CVE-2026-35570: OpenClaude: Sandbox Bypass via Early-Exit Logic Flaw Allows Path Traversal
A logic flaw exists 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.
