At a glance
CVE-2024-7648 is a medium-severity Missing Authorization vulnerability in the Opal Membership WordPress plugin, affecting versions <= 1.2.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed August 2024, reported by Karolina Jankowska.
Vulnerability Overview
The Opal Membership plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.2.4 via the private notes functionality on payments which utilizes WordPress comments. This makes it possible for authenticated attackers, with subscriber-level access and above, to view private notes via recent comments that should be restricted to just administrators.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-862: Missing Authorization
Reaching this weakness in Opal Membership <= 1.2.4 takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.
Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. No fixed build of this plugin is recorded for Opal Membership yet, so installs running <= 1.2.4 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
