Published Aug 21, 2026 · Updated Aug 21, 2026 · Assigned by WPScan

Description

The Welcart e-Commerce WordPress plugin before 2.12.1 does not regenerate the session identifier on authentication and sets the session identifier from a user-supplied request parameter, allowing an unauthenticated attacker to fixate a shop member's session and take over their customer account after the victim logs in through an attacker-crafted request.
