CVE-2026-3449 (GCVE-0-2026-3449)

Vulnerability from cvelistv5 – Published: 2026-03-03 05:00 – Updated: 2026-05-04 05:23
VLAI
Summary
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.
