At a glance
CVE-2026-19949 is a high-severity Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in the All-in-One WP Migration and Backup WordPress plugin, affecting versions <= 7.109. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 7.110; sites on affected versions should update now. Disclosed August 2026, reported by Jack Taylor.
Vulnerability Overview
The All-in-One WP Migration and Backup plugin for WordPress is vulnerable to SQL Injection via archive restore functionality in all versions up to, and including, 7.109 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This can be leveraged to obtain the ai1wm_secret_key when a site administrator performs an archive restore and achieve remote code execution once able to leverage the ai1wm_secret_key value.
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, integrity, availability — full site compromise territory.
CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Reaching this weakness in All-in-One WP Migration and Backup <= 7.109 takes no account at all. SQL injection happens when request data is concatenated into a query instead of being bound as a parameter, letting an attacker change the structure of the statement rather than just its values.
A working injection can read any table the database user can see, which on a WordPress install means user records, password hashes and session or API secrets stored in options. For All-in-One WP Migration and Backup the fix is 7.110: builds <= 7.109 are affected, anything from 7.110 onward is not.
Remediation
Update to version 7.110, or a newer patched version
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: 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 7.110 closes this, and updating the plugin is the step that ends it.
