DescriptionCVE.org

The Mobile App for WooCommerce: ShopApper Mobile App Builder Service for WooCommerce WordPress plugin through 0.4.62 does not check the user's capabilities before allowing a stock-update operation through one of its REST endpoints, allowing any authenticated user, such as a customer or subscriber, to change the stock quantity of arbitrary products.

AnalysisAI

Unauthorized stock manipulation in the ShopApper Mobile App for WooCommerce WordPress plugin (through v0.4.62) permits any authenticated user - including customers or subscribers holding the lowest default WordPress roles - to arbitrarily modify product stock quantities via an unprotected REST endpoint. The root cause is CWE-284 (Improper Access Control): the plugin registers a stock-update REST route without validating WordPress capability permissions, bypassing the access control layer that should restrict such operations to shop managers or administrators. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid WordPress user account on the target site - the default 'Customer' role assigned automatically during WooCommerce checkout registration is sufficient, as is the 'Subscriber' role. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 score of 4.3 (Medium) with vector AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N accurately reflects a network-reachable, low-complexity attack requiring only a low-privilege account, with impact limited to integrity of stock data. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Update the ShopApper Mobile App for WooCommerce plugin to a version beyond 0.4.62 once the vendor releases a patched build; no specific patched version number is confirmed in available data, so administrators should monitor the plugin's WordPress.org repository and the WPScan advisory (https://wpscan.com/vulnerability/0d96cc80-0bba-45e4-8e07-220dc8b82c7d/) for release notifications. … Detailed patch versions, workarounds, and compensating controls in full report.
