At a glance
CVE-2026-96896 is a medium-severity Missing Authorization vulnerability in the Malcure Malware Shield WordPress plugin, affecting versions <= 19.9.6. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high integrity, availability impact). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 19.9.7; sites on affected versions should update now. Disclosed September 2026, reported by Charles Vosburgh.
Vulnerability Overview
The Malcure Malware Shield plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 19.9.6. This is due to a missing capability check on a function. This makes it possible for authenticated attackers, with multisite subsite admin-level access and above, to perform an unauthorized action.
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 integrity, availability.
CWE-862: Missing Authorization
Reaching this weakness in Malcure Malware Shield <= 19.9.6 takes a caller who can reach the endpoint. 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 19.9.7: builds <= 19.9.6 are affected, anything from 19.9.7 onward is not.
Remediation
Update to version 19.9.7, 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 19.9.7 closes this, and updating the plugin is the step that ends it.
