CVE-2026-11782 in Points and Rewards for WooCommerce Plugin
Summary
by MITRE • 07/30/2026
The Points and Rewards for WooCommerce WordPress plugin before 2.10.1 does not have authorisation checks in place on a wallet and points update action that is available to unauthenticated users, and does not verify that the requester owns the account being changed, allowing unauthenticated attackers to arbitrarily modify or corrupt (including driving it negative) the stored wallet balance and loyalty points of any user. Modifying the wallet balance additionally requires the companion Wallet System for WooCommerce Points and Rewards for WooCommerce WordPress plugin before 2.10.1 to be active.

This vulnerability affects the Points and Rewards for WooCommerce plugin version prior to 2101 where improper authorization controls exist in the wallet and points update functionality. The flaw resides in the absence of proper access validation mechanisms that should verify user authentication and account ownership before allowing modifications to financial or loyalty point balances. Attackers can exploit this weakness without requiring valid credentials, making it particularly dangerous as it allows arbitrary manipulation of user accounts. The vulnerability specifically targets the wallet balance and points system components within the WooCommerce ecosystem, where users maintain stored value balances and accumulated loyalty points for purchasing privileges.
The technical implementation fails to validate whether a request originates from an authenticated user who owns the target account, creating a direct path for privilege escalation attacks. This authorization gap enables attackers to submit malicious requests that modify any user's wallet balance or point accumulation, potentially driving accounts into negative balances or manipulating their stored value. The exploitation requires the companion Wallet System plugin to be active, indicating that the vulnerability exists in the interaction between these two components rather than as an isolated flaw. This cross-plugin dependency suggests a broader architectural weakness in how the plugins handle shared data interfaces and user context validation.
The operational impact of this vulnerability extends beyond simple data corruption as it compromises the integrity of customer loyalty programs and financial systems within WooCommerce stores. Unauthenticated attackers can manipulate user balances to gain unfair advantages or cause financial losses for merchants who rely on these point systems for customer retention strategies. The ability to drive accounts negative represents a particularly severe consequence that could lead to system instability, customer disputes, and potential legal ramifications for businesses operating these e-commerce platforms. This vulnerability directly impacts the trust model of WooCommerce loyalty programs where users expect their point balances to be secure and accurately maintained.
Mitigation strategies should focus on implementing proper authorization checks at all entry points for wallet and points modification functions. The solution requires validating user authentication status and verifying account ownership before processing any balance updates or point modifications. Developers must ensure that all API endpoints handling financial data implement robust access controls consistent with industry standards such as those outlined in the CWE 284 Access Control vulnerability classification. Security measures should include session validation, user context verification, and proper input sanitization to prevent unauthorized modifications to account balances. Organizations should also consider implementing rate limiting and monitoring mechanisms to detect unusual patterns of balance modifications that could indicate exploitation attempts.
The vulnerability demonstrates a clear violation of the principle of least privilege and proper access control enforcement as defined in various cybersecurity frameworks including NIST SP 800-53 security controls. The lack of authorization checks represents a fundamental flaw in the plugin's architecture that allows attackers to bypass normal access restrictions through the public-facing wallet update functionality. This weakness could be categorized under the ATT&CK technique T1078 Valid Accounts where adversaries leverage legitimate credentials or account permissions to perform unauthorized modifications within the system. Organizations should immediately update to version 2101 or later of both the Points and Rewards plugin and its companion Wallet System plugin to remediate this vulnerability and ensure proper authorization controls are in place for all financial transaction processing functions within their e-commerce platforms.
