What is CVE-2026-109188?

The jshERP software, up to version 3.6, exhibits a missing authorization vulnerability that empowers low-privilege authenticated users. This flaw allows them to leverage add and import endpoints—specifically /account/add, /material/add, and /material/importExcel—to generate tenant-wide master data without appropriate role checks. Attackers can exploit this weakness through crafted POST requests, enabling the creation of settlement accounts, products with initial stock, departments, and dictionary entries, thus posing significant risks to data integrity and user access control.

Affected Version(s)

jshERP 0 <= 3.6

Exploit Proof of Concept (PoC)
