CVE-2026-6419

CVSS v3.1

8.8

High

VectorAV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Name of the Vulnerable Software and Affected Versions WishList Member versions prior to 3.30.2
Description An issue exists where missing authorization allows for privilege escalation. The ajax get screen() function fails to perform necessary capability and nonce checks. Authenticated attackers with Subscriber-level access or higher can provide an arbitrary admin screen identifier through the data[url] parameter. This action causes the plugin to load and execute the administrative API configuration template without authorization, returning the plugin's plaintext REST API Secret Key within the AJAX JSON response. An attacker possessing this key can authenticate to the API, create a membership level with the administrator WordPress role, and register an administrator-level user account, leading to a complete site takeover.
Recommendations Update to a version later than 3.30.1. As a temporary workaround, restrict access to the ajax get screen() function to prevent unauthorized users from triggering the administrative API configuration template.
