# CVE-2026-1280: Frontend File Manager Plugin \<= 23.5 - Missing Authorization to Unauthenticated Arbitrary File Sharing via 'file\_id' Parameter

- Severity: CVSS 7.5 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- CISA SSVC: exploitation=none, automatable=yes, technicalImpact=partial

## Affected

- nmedia Frontend File Manager Plugin: through 23.5

## Description

The Frontend File Manager Plugin for WordPress is vulnerable to unauthorized file sharing due to a missing capability check on the 'wpfm_send_file_in_email' AJAX action in all versions up to, and including, 23.5. This makes it possible for unauthenticated attackers to share arbitrary uploaded files via email by supplying a file ID. Since file IDs are sequential integers, attackers can enumerate all uploaded files on the site and exfiltrate sensitive data that was intended to be restricted to administrators only.
