At a glance
CVE-2024-10527 is a low-severity Missing Authorization vulnerability in the Spacer WordPress plugin, affecting versions <= 3.0.7. It carries a CVSS score of 3.1 (reachable over the network). 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 January 2025, reported by Trương Hữu Phúc (truonghuuphuc).
Vulnerability Overview
The Spacer plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the motech_spacer_callback() function in all versions up to, and including, 3.0.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view limited setting information.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.
CWE-862: Missing Authorization
Spacer <= 3.0.7 carries this weakness at motech_spacer_callback(), and reaching it 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 Spacer yet, so installs running <= 3.0.7 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.
