Vulnerability from github – Published: 2026-06-24 09:30 – Updated: 2026-06-24 09:30

Details

The Generate Security.txt plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.0.12. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete the site's security.txt file from the server filesystem or create the .well-known directory by directly invoking the delete_securitytxt or create_wellknown_folder AJAX actions.

Severity

4.3 (Medium)


                  
                    CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N
