Yggdrasil-worker-package-manager: yggdrasil-worker-package-manager: path traversal via unsanitized repo name in addrepo/removerepo

Published Nov 12, 2026 · Updated Nov 13, 2026 · Assigned by redhat

Description

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.
