CVE-2026-49009 Details
Description
Northern.tech Mender Server v4.1.0, v4.0.1 and below, and fixed in v4.1.1 and v4.0.2 allows Directory Traversal.
A directory traversal vulnerability has been identified in Northern.tech Mender Server versions 4.1.0, 4.0.1 and earlier. The issue arises from improper input sanitization in the endpoint for creating artifacts, which can be accessed through the UI or API. This flaw allows an attacker to include path traversal sequences in requests, enabling them to access and modify files outside the intended directory. In a multi-tenant environment like hosted Mender, this could lead to injecting malicious code into artifacts, potentially compromising the containers of other users.
Users are advised to upgrade to Mender Server versions 4.1.1 or 4.0.2. Detailed upgrade instructions are available in the Mender documentation.
