CVE-2026-94050
CVE-2026-94050 is an information disclosure vulnerability in the ubus JSON‑RPC interface of D‑Link DIR‑X1860Z routers up to firmware 1.0.2.2
Overview
CVE-2026-94050 is an information disclosure vulnerability in the ubus JSON‑RPC interface of D‑Link DIR‑X1860Z routers up to firmware 1.0.2.220120.165402. An attacker on the local network can retrieve sensitive data by manipulating routerd.wificfg_get/routerd.get_rand_key. The flaw is mitigated by upgrading to firmware 1.0.7.260821.161908.
Description
A vulnerability has been found in D-Link DIR-X1860Z up to 1.0.2.220120.165402. Affected is the function routerd.wificfg_get/routerd.get_rand_key of the component ubus JSON-RPC interface. Such manipulation leads to information disclosure. The attack must be carried out from within the local network. Upgrading to version 1.0.7.260821.161908 is able to address this issue. It is suggested to upgrade the affected component. This vulnerability only affects products that are no longer supported by the maintainer.
Impact
Confidentiality: sensitive configuration and network data may be exposed. Availability: not directly impacted. Integrity: not directly impacted. Defenders should monitor for anomalous JSON‑RPC traffic and ensure only trusted devices can access the ubus interface.
Remediation
Upgrade the router firmware to version 1.0.7.260821.161908 or later. If upgrade is not possible, disable the ubus JSON‑RPC interface or restrict it to localhost only, and block external access to the relevant ports.
Risk context
Medium severity (CVSS v3 4.3, v4 5.3). No EPSS data available. The vulnerability is local‑network only, so risk is moderate but still requires patching to prevent data leakage.
