- Severity: CVSS 6.4 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N

## Affected

- frankpw FPW Category Thumbnails: through 1.9.5

## Description

The FPW Category Thumbnails plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'id' parameter of the 'fpw_fs_get_file' AJAX action in all versions up to, and including, 1.9.5. This is due to insufficient input sanitization and output escaping. 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's settings page.
