This affects all versions of package wincred. If attacker-controlled user input is given to the getCredential function, it is possible for an attacker to execute arbitrary commands. This is due to use of the child_process exec function without input sanitization.

Exploit prediction

1.34% chance of exploitation in the next 30 days, higher than 71% of all scored CVEs (FIRST EPSS, 2026-11-08).
