NVD Description

Note: Versions mentioned in the description apply only to the upstream pcs-snmp package and not the pcs-snmp package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

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.
