CVE-2025-15671: CWE-287 Improper Authentication in Welcart e-Commerce
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.
AI Analysis
Technical Summary
The Welcart e-Commerce WordPress plugin prior to version 2.12.1 does not regenerate the session identifier upon user authentication and permits the session ID to be set from a user-supplied request parameter. This improper handling of session management (CWE-287) allows an attacker to perform session fixation attacks. By crafting a request that sets a known session ID, an attacker can cause a victim to authenticate with that session, enabling the attacker to hijack the victim's customer account.
Potential Impact
An attacker can fixate a session identifier for a victim and take over the victim's customer account after they log in. This compromises the confidentiality and integrity of the victim's account within the e-commerce platform, potentially leading to unauthorized access to personal and transactional data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should monitor vendor communications for updates. Avoid using affected versions in production environments if possible.
