Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') pada nyariv sandboxjs. Skor CVSS 3.1 4.7 (Medium) menurut NVD.

Deskripsi (NVD)

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.35, SandboxJS timers have an execution-quota bypass. A global tick state (`currentTicks.current`) is shared between sandboxes. Timer string handlers are compiled at execution time using that global tick state rather than the scheduling sandbox's tick object. In multi-tenant / concurrent sandbox scenarios, another sandbox can overwrite `currentTicks.current` between scheduling and execution, causing the timer callback to run under a different sandbox's tick budget and bypass the original sandbox's execution quota/watchdog. Version 0.8.35 fixes this issue.
