Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded append operations on state lists and strings (such as text lines or image histories) can lead to rapid memory consumption, enabling remote attackers to crash the server via Out-Of-Memory (OOM) errors. This risk is critical as it directly affects application availability under standard operational use.
Denial of Service: Unhandled exceptions during disk IO, such as a FileNotFoundError during environment file deletion, can crash the entire backend service. Robust exception handling must wrap all system calls to prevent localized client failures from escalating into global service disruption.
