nopCommerce 4.90.0 is vulnerable to Cross Site Scripting (XSS) in the product management functionality. Malicious payloads inserted into the "Product Name" and "Short Description" fields are stored in the backend database and executed automatically whenever a user views the affected pages.
nopCommerce v4.70 and prior, and version 4.80.3, does not invalidate session cookies after logout or session termination, allowing an attacker who has a
a valid session cookie access to privileged endpoints (such as /admin) even after the legitimate user has logged out, enabling session hijacking. Any version above 4.70 that is not 4.80.3 fixes the vulnerability.
nopCommerce 4.40.3 is vulnerable to XSS in the Product Name at /Admin/Product/Edit/[id]. Each time a user views the product in the shop, the XSS payload fires.
Nopcommerce 4.70.1 is vulnerable to Cross Site Scripting (XSS) via the combined "AddProductReview.Title" and "AddProductReview.ReviewText" parameter(s) (Reviews) when creating a new review.
Multiple open redirect vulnerabilities in NopCommerce 4.10 through 4.50.1 allow remote attackers to conduct phishing attacks by redirecting users to attacker-controlled web sites via the returnUrl parameter, processed by the (1) ChangePassword function, (2) SignInCustomerAsync function, (3) SuccessfulAuthentication method, or (4) NopRedirectResultExecutor class.
In nopCommerce 4.50.1, an open redirect vulnerability can be triggered by luring a user to authenticate to a nopCommerce page by clicking on a crafted link.
nopCommerce 4.50.1 is vulnerable to Cross Site Scripting (XSS) via the "Text" parameter (forums) when creating a new post, which allows a remote attacker to execute arbitrary JavaScript code at client browser.
nopCommerce 4.50.1 is vulnerable to Cross Site Scripting (XSS). At Apply for vendor account feature, an attacker can upload an arbitrary file to the system.
nopCommerce 4.50.1 is vulnerable to Cross Site Scripting (XSS). An attacker (role customer) can inject javascript code to First name or Last name at Customer Info.
In nopCommerce 4.30, a Reflected XSS issue in the Discount Coupon component allows remote attackers to inject arbitrary web script or HTML through the Filters/CheckDiscountCouponAttribute.cs discountcode parameter.
nopCommerce Store 4.30 is affected by cross-site scripting (XSS) in the Schedule tasks name field. This vulnerability can allow an attacker to inject the XSS payload in Schedule tasks and each time any user will go to that page of the website, the XSS triggers and attacker can able to steal the cookie according to the crafted payload.
nopCommerce v4.2.0 allows privilege escalation via file upload in Presentation/Nop.Web/Admin/Areas/Controllers/PluginController.cs via Admin/FacebookAuthentication/Configure because it is possible to upload a crafted Facebook Auth plugin.
