SenseLive X3050 version V1.523 contains a vulnerability (CVE-2026-35503) where the authentication logic is implemented entirely on the client side, relying on hardcoded credentials embedded in browser-executed scripts instead of server-side verification. This design flaw (CWE-798) exposes sensitive authentication parameters to anyone accessing the login page, enabling unauthorized administrative access. The vulnerability has a CVSS 4.0 base score of 9.3, reflecting its critical impact. No patch or official remediation guidance has been published, and the product is not a cloud service, so remediation depends on vendor updates.

An attacker with access to the login page can retrieve hardcoded credentials from client-side scripts and bypass authentication controls to gain unauthorized administrative access to the SenseLive X3050 device. This could lead to full control over the device's management interface, potentially compromising device integrity and availability. No known exploits have been reported in the wild so far.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the device's management interface to trusted networks and users only to reduce exposure. Monitor vendor communications for updates regarding patches or official mitigations.
