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.

Affected products and versions

  • servmask All-in-One WP Migration Unlimited Extension — Up to and including 2.84
