CVE-2025-29788: The Syliud PayPal Plugin is the Sylius Core Team’s plugin for the PayPal Commerce Platform. A vulnerability in versions prior to 1.6.1, 1.7.1, and 2.0.1 allows users to manipulate the final payment amount processed by PayPal. If a user modifies the item quantity in their shopping cart after initiating the PayPal Express Checkout process, PayPal will not receive the updated total amount. As a result, PayPal captures only the initially transmitted amount, while Sylius incorrectly considers the order fully paid based on the modified total. This flaw can be exploited both accidentally and intentionally, potentially enabling fraud by allowing customers to pay less than the actual order value. Attackers can intentionally pay less than the actual total order amount, business owners may suffer financial losses due to underpaid orders, and integrity of payment processing is compromised. The issue is fixed in versions 1.6.1, 1.7.1, 2.0.1, and above. To resolve the problem in the end application without updating to the newest patches, there is a need to overwrite `ProcessPayPalOrderAction`, `CompletePayPalOrderFromPaymentPageAction`, and `CaptureAction` with modified logic.
The exploitability of CVE-2025-29788 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
With low attack complexity and no required privileges, CVE-2025-29788 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-29788, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-29788, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
