CVE-2026-18157 (GCVE-0-2026-18157)

Vulnerability from cvelistv5 – Published: 2026-07-31 02:38 – Updated: 2026-07-31 15:58

Title

Yggdrasil-worker-package-manager: yggdrasil-worker-package-manager: remote code execution via apt argument injection

Summary

A flaw was found in yggdrasil-worker-package-manager. A local attacker with existing access to the system could exploit an argument injection vulnerability in the APT backend. This allows specially crafted package names, which begin with a hyphen, to be misinterpreted as command options by apt-get. Successful exploitation could lead to remote code execution (RCE) with root privileges, enabling the attacker to fully compromise the system's integrity, confidentiality, and availability.

Severity
