CVE-2026-8736

Description

A security flaw has been discovered in Oinone Pamirs up to 7.2.0. This vulnerability affects the function request.getParameter of the file LocalFileClient.java of the component RestController. Performing a manipulation of the argument uniqueFileName results in path traversal. The attack may be carried out on the physical device. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
