CVE-2026-105621 · Severity: medium · CVSS 5.4 · Published 2026-10-06

jshERP is an open-source ERP system for small and medium businesses that manages sales, purchasing, inventory, and financial operations. A flaw in the financial receipt update handler allows authenticated users to modify audited financial receipts and payments without performing a reverse-audit first, bypassing the approval workflow and corrupting debt settlement records. Additionally, users can modify financial documents belonging to other users in the same tenant.

## How to fix


Load and validate the persisted audit status (status='0' for unaudited) in the update handler before allowing modifications, rejecting updates to audited documents. Require an explicit reverse-audit operation before any changes to audited financial documents, and enforce caller ownership and financial-edit permissions on the endpoint.</anigation>
</invoke>

## Technical details

The updateAccountHeadAndDetail function in AccountHeadService fails to validate the persisted audit status before updating financial document headers, instead trusting the caller-supplied status value. The update path performs only bill-number uniqueness checks and recalculates settlement details, while the deletion path correctly enforces audit-status validation. An authenticated attacker can modify document amounts and settlement allocations while they remain marked as audited, and the endpoint lacks ownership or data-scope restrictions allowing cross-user modifications within the same tenant.
