At a glance
CVE-2026-81810 is a medium-severity Improper Privilege Management vulnerability in the All-in-One WP Migration and Backup WordPress plugin, affecting versions <= 7.110. It carries a CVSS score of 4.7 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Admin level or above. The issue is fixed in version 7.111; sites on affected versions should update now. Disclosed September 2026, reported by Charles Vosburgh.
Vulnerability Overview
The All-in-One WP Migration and Backup plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 7.110. This is due to insufficient restriction on the capabilities a user may grant themselves. This makes it possible for authenticated attackers, with admin-level access and above, to elevate their privileges beyond those intended for their role.
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-269: Improper Privilege Management
Reaching this weakness in All-in-One WP Migration and Backup <= 7.110 takes an account at Admin level or above. Improper privilege management means the code lets an account end up with capabilities its role should not have.
It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For All-in-One WP Migration and Backup the fix is 7.111: builds <= 7.110 are affected, anything from 7.111 onward is not.
Remediation
Update to version 7.111, 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: All-in-One WP Migration and Backup 7.111 closes this, and updating the plugin is the step that ends it.
