SandboxJS timers have an execution-quota bypass (cross-sandbox currentTicks race)
Résumé
SandboxJS timers have an execution-quota bypass (cross-sandbox currentTicks race)
Description d'origine
La description telle que publiée par la source (souvent en anglais).
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.
