FKIE_CVE-2026-23520

Vulnerability from fkie_nvd - Published: 2026-01-15 20:16 - Updated: 2026-01-16 15:55
Severity ?
9.0 (Critical) - CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H
Summary
Arcane provides modern docker management. Prior to 1.13.0, Arcane has a command injection in the updater service. Arcane’s updater service supported lifecycle labels com.getarcaneapp.arcane.lifecycle.pre-update and com.getarcaneapp.arcane.lifecycle.post-update that allowed defining a command to run before or after a container update. The label value is passed directly to /bin/sh -c without sanitization or validation. Because any authenticated user (not limited to administrators) can create projects through the API, an attacker can create a project that specifies one of these lifecycle labels with a malicious command. When an administrator later triggers a container update (either manually or via scheduled update checks), Arcane reads the lifecycle label and executes its value as a shell command inside the container. This vulnerability is fixed in 1.13.0.
