At a glance
CVE-2025-7772 is a medium-severity Missing Authorization vulnerability in the Malcure Malware Shield WordPress plugin, affecting versions <= 16.8. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 16.9; sites on affected versions should update now. Disclosed June 2025, reported by Arkadiusz Hydzik.
Vulnerability Overview
The Malcure Malware Scanner — #1 Toolset for WordPress Malware Removal plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to, and including, 16.8 via the wpmr_inspect_file() function due to a missing capability check. This makes it possible for authenticated attackers, with subscriber-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
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. A successful exploit has high impact on confidentiality.
CWE-862: Missing Authorization
Malcure Malware Shield <= 16.8 carries this weakness at wpmr_inspect_file(), 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. For Malcure Malware Shield the fix is 16.9: builds <= 16.8 are affected, anything from 16.9 onward is not.
Remediation
Update to version 16.9, or a newer patched version
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. None of that substitutes for the fix: Malcure Malware Shield 16.9 closes this, and updating the plugin is the step that ends it.
