CVE-2026-105573: newbee-mall Business Logic Vulnerability

CVE-2026-105573 Overview

CVE-2026-105573 affects newbee-ltd newbee-mall versions up to 2.7.5. The flaw resides in the Shopping Cart Quantity Handler component, specifically in the /jshERP-boot/accountHead/updateAccountHeadAndDetail endpoint. An authenticated remote attacker can manipulate the goodsCount argument to trigger business logic errors [CWE-840]. The vulnerability is classified as a business logic flaw rather than a memory or injection issue. A public exploit disclosure exists, and the project maintainers have not responded to the issue report at the time of publication.

Critical Impact
Remote authenticated attackers can abuse the shopping cart quantity handler to induce business logic errors, potentially impacting transaction integrity in e-commerce deployments.

Affected Products

newbee-ltd newbee-mall versions up to and including 2.7.5

Technical Details for CVE-2026-105573

Vulnerability Analysis

The vulnerability is a business logic error [CWE-840] in the newbee-mall shopping cart workflow. The updateAccountHeadAndDetail handler processes a goodsCount parameter supplied by the client without enforcing the business rules that govern quantity semantics. An attacker with low-privileged account access can submit crafted values for goodsCount to the endpoint and bypass intended checkout logic. Because the issue stems from workflow design rather than a parsing fault, standard input sanitization will not remediate it. The Exploit Prediction Scoring System places active exploitation probability in the lower tier, consistent with the limited impact scope of a logic flaw constrained to business state.

Root Cause

The root cause is insufficient server-side validation of quantity constraints in the cart update workflow. The handler trusts client-supplied goodsCount values and does not reconcile them against product inventory, allowed ranges, or pricing invariants. This permits state manipulation that violates the intended e-commerce business logic.

Attack Vector

An attacker interacts remotely over the network with low privileges (an authenticated account) and no user interaction. By issuing a crafted HTTP request to /jshERP-boot/accountHead/updateAccountHeadAndDetail with a manipulated goodsCount field, the attacker triggers inconsistent cart or order state. Public exploit details are referenced in the GitHub Issue #127 Discussion and the VulDB CVE-2026-105573 record.

No verified proof-of-concept code is published in a form suitable for inclusion here. See the VulDB Vulnerability #413632 entry for additional technical context.

Detection Methods for CVE-2026-105573

Indicators of Compromise

HTTP POST or PUT requests to /jshERP-boot/accountHead/updateAccountHeadAndDetail with anomalous goodsCount values such as negative numbers, zero, or extreme magnitudes.
Order or cart records in the application database containing quantities that violate configured product constraints.
Repeated authenticated requests from a single session rapidly modifying cart quantities on the same account head.

Detection Strategies

Review application logs for updateAccountHeadAndDetail invocations and flag any goodsCount values outside expected business ranges.
Correlate cart update events with downstream order totals to detect price or inventory inconsistencies.
Deploy web application firewall rules that validate numeric bounds on quantity parameters at the perimeter.

Monitoring Recommendations

Enable verbose logging on the newbee-mall and jshERP-boot services, including authenticated user identifiers tied to cart operations.
Alert on reconciliation failures between cart state, inventory decrement operations, and payment totals.
Monitor for unusual patterns of low-privilege account activity targeting cart endpoints.

How to Mitigate CVE-2026-105573

Immediate Actions Required

Restrict access to the /jshERP-boot/accountHead/updateAccountHeadAndDetail endpoint to trusted authenticated roles only.
Enforce server-side validation that rejects goodsCount values outside permitted ranges before persisting cart or order state.
Audit existing orders and carts for quantities that violate business rules and reconcile with inventory.

Patch Information

As of the NVD publication date of 2026-10-06, the newbee-ltd project has not responded to the issue report and no official patch is available. Monitor the newbee-mall GitHub repository and GitHub Issue #127 for upstream fixes.

Workarounds

Add a reverse proxy or API gateway rule that enforces integer bounds and rejects non-positive values on the goodsCount parameter.
Implement a server-side middleware layer that revalidates cart totals, inventory availability, and pricing before any order commit.
Limit the exposure of the jshERP-boot administrative endpoints to internal networks where feasible.
