What is CVE-2026-94536?

The Lamp-cloud software, up to version 5.10.0, is susceptible to an information disclosure vulnerability due to inadequate validation of the 'employeeId' parameter in the '/anyone/visible/resource' endpoint. This flaw permits authenticated users to exploit the system, enabling them to read roles and permissions assigned to other employees by supplying arbitrary 'employeeId' values. Consequently, attackers can enumerate role codes, permission codes, and the complete front-end router tree without appropriate authorization checks.

Affected Version(s)

lamp-cloud 0 <= 5.10.0

Exploit Proof of Concept (PoC)
