CVE-2024-45366
📋 TL;DR
Welcart e-Commerce versions before 2.11.2 contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into web pages. When exploited, these scripts execute in users' browsers, potentially stealing session cookies, redirecting to malicious sites, or performing actions on behalf of authenticated users. This affects all Welcart e-Commerce websites running vulnerable versions.
