CVE-2026-86114 Details
Description
Arcane versions before 2.0.0 fail to properly restrict template operations, allowing default user role accounts to create, modify, and delete compose templates including instance-wide defaults. Attackers can inject malicious container configurations with privileged settings or host path mounts that execute with administrative privileges when deployed by administrators.
A vulnerability exists in Arcane versions prior to 2.0.0, where the application fails to properly enforce authorization on template management operations. This flaw allows users with default roles to create, modify, and delete compose templates, including system-wide defaults. Exploitation of this vulnerability could lead to the injection of malicious container configurations with elevated privileges, especially when these templates are deployed by administrators.
Users can update to Arcane version 2.0.0 or later, where this vulnerability has been addressed.
