DescriptionCVE.org

The Wallet for WooCommerce WordPress plugin before 1.6.10 does not verify the amount actually collected for a wallet top-up before crediting the wallet, allowing customers to top up their wallet balance for less than its value.

AnalysisAI

Financial/business-logic bypass in the Wallet for WooCommerce WordPress plugin (all versions before 1.6.10) lets a customer credit their wallet balance for less than the amount actually paid, because the plugin credits the top-up before confirming the sum the payment gateway actually collected. Any registered store customer can effectively mint store credit at a discount, causing direct monetary loss to the merchant. …

Vulnerability AssessmentAI

Exploitation Requires the Wallet for WooCommerce plugin (before 1.6.10) installed and the wallet top-up feature enabled on a WooCommerce store that accepts customer accounts. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The published CVSS 3.1 score is 9.1 (AV:N/AC:L/PR:N/UI:N, C:H/I:H/A:N), but that vector overstates real-world severity in two ways worth flagging: it marks PR:N (unauthenticated) while the description explicitly scopes the actor to 'customers,' implying a registered account is required, and it rates C:H even though the flaw's true impact is integrity/financial fraud, not confidentiality disclosure - verify the authentication assumption against the vendor advisory. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker registers as an ordinary store customer and initiates a wallet top-up, then manipulates the payment flow so the gateway captures a smaller amount (or a partial/failed capture) than the top-up value while the plugin still credits the full requested balance. The attacker repeatedly buys store credit below face value and spends it on goods, netting a direct financial gain; public PoC guidance from WPScan lowers the skill barrier.
Remediation Vendor-released patch: upgrade the Wallet for WooCommerce plugin to version 1.6.10 or later, which adds verification of the amount actually collected before crediting the wallet. … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Identify all WordPress instances running Wallet for WooCommerce versions before 1.6.10 and audit wallet transaction logs for patterns indicating exploitation. …
