Recurring patterns

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

Insecure Temporary File: The executor set up IPC sockets using vulnerable filesystem /tmp paths, exposing the service to socket hijacking and collision risks on multi-user systems. It was migrated to abstract Unix domain sockets.

Denial of Service: Lack of prompt length validation allowed excessively long input sequences to pass through the router, exhausting downstream resources and causing service denial.

Untrusted Deserialization: Manipulation of local checkpoint arguments (ckpt_path/quant_ckpt_dir) via torch.load allows local attackers to execute arbitrary code.
