CVE-2023-43484Network attack vector

Unauthenticated script execution in logged-in browsers

Published Sep 26, 2023 · Updated Sep 24, 2024

Cross-site scripting in Welcart e-Commerce 2.7 through 2.8.21 allows remote attackers to execute scripts in logged-in users' browsers. The public advisory identifies the Item List page but does not disclose the input, handler, or missing output-neutralization operation. Exploitation requires a logged-in user to open attacker-controlled content, after which the injected script runs in that user's browser context.
