The Welcart e-Commerce WordPress plugin up to and including 2.12.5 accepts a user-supplied member ID that lets an unauthenticated visitor overwrite another member's email address and password. An attacker can then log in as that member and take over the account.

2.12.5 and below.2.12.5 (the sources do not name the fixed release).Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
The Welcart e-Commerce plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.12.5 via the 'member[ID]' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to overwrite any existing Welcart shop-member account's email address and password by supplying that member's numeric ID, then authenticate as that member to achieve full account takeover. The only authentication barrier is a wp_verify_nonce() check against a nonce printed to every unauthenticated visitor on the auto-published New Enrollment Form, meaning no existing account, no WordPress login, and no non-default configuration is required to exploit this vulnerability.
