Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Code Execution: Serializable closures used in queued jobs were unsigned, allowing tampering that could lead to arbitrary code execution when deserialized by the worker.
Denial of Service: Default maxTries of 0 allowed infinite retry loops for failing jobs, exhausting worker resources and blocking the queue.
Denial of Service: Daemon workers ran jobs in the same process without timeouts, so a single hung job could block the entire worker indefinitely.
