CVE-2026-18379NVD

Vulnerability Summary

A flaw was found in yggdrasil-worker-package-manager. An authenticated attacker can exploit this issue to achieve arbitrary file modification or potential privilege escalation. The vulnerability exists because repository management operations fail to sanitize directory traversal sequences (such as '../') within repository names. By supplying a crafted repository name, an attacker can manipulate the root-level worker process into creating or deleting files outside the intended directory, compromising host system integrity.
