NVD description
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.

🚨High - yggdrasil-worker-package-manager APT Backend apt-get Argument Injection (CVE-2026-18157)
In yggdrasil-worker-package-manager's APT backend, unsanitized package names are passed to apt-get; names starting with '-' are treated as command options, enabling argument injection. A local attacker with system access can trigger apt-get option abuse to execute attacker-controlled commands as root, leading to full system compromise. Normal package names not beginning with '-' are not affected.
👉Affected: yggdrasil-worker-package-manager (all versions)
