At a glance

CVE-2026-12898 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the All-in-One WP Migration and Backup WordPress plugin, affecting versions <= 7.105. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 7.106; sites on affected versions should update now. Disclosed June 2026, reported by Jakub Herman.

Vulnerability Overview

The All-in-One WP Migration and Backup plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in all versions up to, and including, 7.105. This makes it possible for unauthenticated attackers to write logs to an arbitrary location.

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 privileges on the target site, and no interaction from a victim user.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in All-in-One WP Migration and Backup <= 7.105 takes a caller who can reach the endpoint. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For All-in-One WP Migration and Backup the fix is 7.106: builds <= 7.105 are affected, anything from 7.106 onward is not.

Remediation

Update to version 7.106, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to All-in-One WP Migration and Backup: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: All-in-One WP Migration and Backup 7.106 closes this, and updating the plugin is the step that ends it.
