Vulnerability Title
All-in-One WP Migration Unlimited Extension <= 2.84 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'ai1wm_backups_path' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The All-in-One WP Migration Unlimited Extension plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'ai1wm_backups_path' parameter in all versions up to, and including, 2.84. This is due to insufficient input sanitization and output escaping on user-supplied attributes combined with missing authorization checks on the settings() function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever an administrator accesses the plugin settings page. The vulnerability was partially patched in version 2.84.
