# CVE-2021-24905: Advanced Contact form 7 DB \< 1.8.7 - Subscriber+ Arbitrary File Deletion

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 1.8.7
- Published: 2022-03-21 · Updated: 2024-08-03

## Affected

- Unknown Advanced Contact form 7 DB: from 1.8.7, fixed in 1.8.7

## Description

The Advanced Contact form 7 DB WordPress plugin before 1.8.7 does not have authorisation nor CSRF checks in the acf7_db_edit_scr_file_delete AJAX action, and does not validate the file to be deleted, allowing any authenticated user to delete arbitrary files on the web server. For example, removing the wp-config.php allows attackers to trigger WordPress setup again, gain administrator privileges and execute arbitrary code or display arbitrary content to the users.
