Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Command Injection: User-supplied SMB parameters were interpolated directly into shell mount commands. While mitigated by utilizing temporary files for credentials, any new network storage utilities must strictly avoid shell execution for mounting filesystems.

Auth Bypass: WebSocket upgrades bypass standard HTTP middleware authentication. If custom upgrade paths do not explicitly validate session states, unauthenticated connections can gain full protocol-level access.

Remote Code Execution: The platform relies on the underlying Linux kernel and is exposed to kernel-level vulnerabilities (like DirtyFrag and algif_aead bugs) unless vulnerable modules are actively blacklisted during system boot.
