CVE-2026-18274

Heimdall Data Database Proxy uploadJar Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Heimdall Data Database Proxy. Authentication is required to exploit this vulnerability. The specific flaw exists within the uploadJar method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-28603.
