Vulnerability Description
Versions of the package @tootallnate/once before 3.0.1 are vulnerable to Incorrect Control Flow Scoping in promise resolving when AbortSignal option is used. The Promise remains in a permanently pending state after the signal is aborted, causing any await or .then() usage to hang indefinitely. This can cause a control-flow leak that can lead to stalled requests, blocked workers, or degraded application availability.

Vulnerability Description
@tootallnate/once是Nathan Rajlich个人开发者的一个JavaScript代码库。 @tootallnate/once 3.0.1之前版本存在安全漏洞，该漏洞源于使用AbortSignal选项时，Promise解析存在控制流作用域错误，信号中止后Promise保持永久挂起状态，导致任何await或.then()使用无限期挂起，这可能引起控制流泄漏，导致请求停滞、工作线程阻塞或应用程序可用性降低。
