What is CVE-2026-109184?

The improper authorization vulnerability in jshERP versions up to 3.6 enables low-privilege authenticated users to gain unauthorized access to sensitive settlement account ledgers. This occurs when users can exploit the GET /account/findAccountInOutList endpoint by supplying arbitrary account IDs, effectively bypassing intended data access restrictions. Consequently, attackers, even with limited privileges, are able to view sensitive details such as bill numbers, counterparties, amounts, and remarks related to other users' data within the same tenant.

Affected Version(s)

jshERP 0 <= 3.6

Exploit Proof of Concept (PoC)
