CVE-2025-8198 in MinimogWP Plugin
Summary
by MITRE • 07/26/2025
The MinimogWP – The High Converting eCommerce WordPress Theme theme for WordPress is vulnerable to price manipulation in all versions up to, and including, 3.9.0. This is due to an insufficient check on quantity values when changing quantities in the cart. This makes it possible for unauthenticated attackers to add items to the cart and adjust the quantity to a fractional amount, causing the price to change based on the fractional amount. The vulnerability cannot be exploited if WooCommerce version 9.8.2+ is installed.

The CVE-2025-8198 vulnerability affects the MinimogWP eCommerce WordPress theme, presenting a significant price manipulation risk that exploits insufficient input validation mechanisms within the shopping cart functionality. This vulnerability exists in all versions up to and including 3.9.0, making it a widespread concern for WordPress store operators who have not updated their theme installations. The flaw specifically targets the quantity validation process during cart modifications, creating an avenue for unauthorized price adjustments that can result in financial loss for merchants and potential exploitation by malicious actors.
The technical implementation of this vulnerability stems from inadequate sanitization and validation of quantity parameters when users modify their cart items. Attackers can exploit this weakness by adding products to the cart and then manipulating the quantity values to fractional amounts, which directly influences the final calculated price. This type of vulnerability falls under the CWE-191 category of Integer Underflow, where improper handling of numeric inputs leads to unexpected behavior in calculations. The vulnerability operates at the application layer, specifically within the theme's cart processing logic, and represents a classic example of insufficient input validation that allows attackers to manipulate system behavior through crafted data inputs.
The operational impact of this vulnerability extends beyond simple price manipulation, creating potential risks for e-commerce businesses that rely on accurate pricing mechanisms. Unauthenticated attackers can exploit this flaw to artificially inflate or deflate product costs, potentially leading to revenue loss, customer confusion, and trust erosion. The vulnerability's exploitation does not require authentication, making it particularly dangerous as it can be leveraged by anyone with access to the affected website. This type of attack aligns with attack techniques documented in the MITRE ATT&CK framework under the T1211 category of Exploitation for Privilege Escalation, where attackers manipulate application logic to achieve unauthorized outcomes.
The vulnerability's remediation path is straightforward yet critical for maintaining system integrity. The most effective mitigation strategy involves updating the MinimogWP theme to version 3.9.1 or later, where the quantity validation has been properly implemented. Additionally, merchants should ensure their WooCommerce installation is updated to version 9.8.2 or higher, as this version includes protective measures that prevent exploitation of the vulnerability. Security best practices recommend implementing comprehensive input validation for all user-supplied data, particularly numeric values that influence financial calculations, as outlined in OWASP Top Ten category A03: Injection, which emphasizes the importance of proper data sanitization to prevent manipulation attacks.
