The All-in-One WP Migration and Backup WordPress plugin before 7.108 does not restrict its migration import functionality to network administrators on multisite installations, allowing an administrator of a single subsite to execute arbitrary PHP code across the entire network.
AnalysisAI
Privilege escalation in the All-in-One WP Migration and Backup WordPress plugin (versions prior to 7.108) on multisite installations allows subsite administrators to execute arbitrary PHP code across the entire WordPress network. The vulnerability stems from missing access control enforcement on the migration import feature, which should be restricted to network-level administrators but is accessible to lower-privileged subsite admins. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires all of the following: (1) a WordPress multisite installation - standard single-site WordPress is not affected under any circumstances; (2) All-in-One WP Migration and Backup plugin installed at a version prior to 7.108; (3) the attacker must hold authenticated subsite administrator credentials (CVSS PR:H) - unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) correctly reflects the high-privilege prerequisite (PR:H) while noting full CIA impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with subsite administrator credentials on a WordPress multisite network crafts a malicious migration archive embedding a PHP webshell or backdoor, then triggers the plugin's migration import function - which improperly permits subsite admins to invoke this network-level operation. The PHP payload executes server-side with network-wide scope, granting the attacker persistent code execution across all subsites. … |
| Remediation | Upgrade the All-in-One WP Migration and Backup plugin to version 7.108 or later, which contains the vendor-released patch addressing the access control deficiency. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of all WordPress multisite installations using the All-in-One WP Migration and Backup plugin and identify those running versions prior to 7.108. …
