What is CVE-2026-94414?

jshERP prior to version 3.6 contains a vulnerability in the POST /userBusiness/updateBtnStr endpoint. This flaw occurs due to the absence of an authorization check, allowing authenticated users to potentially alter role-specific button-permission configurations. Malicious actors can exploit this weakness by supplying arbitrary roleId and btnStr parameters, enabling them to overwrite permissions without proper validation and gain unauthorized access to functionalities in the system.

Affected Version(s)

jshERP 0 <= 3.6
