Cross-site scripting (XSS) vulnerability in admin/htaccess/bpsunlock.php in the BulletProof Security plugin before .51.1 for WordPress allows remote attackers to inject arbitrary web script or HTML via the dbhost parameter.

SQL injection vulnerability in admin/htaccess/bpsunlock.php in the BulletProof Security plugin before .51.1 for WordPress allows remote authenticated users to execute arbitrary SQL commands via the tableprefix parameter.

Server-side request forgery (SSRF) vulnerability in admin/htaccess/bpsunlock.php in the BulletProof Security plugin before .51.1 for WordPress allows remote attackers to trigger outbound requests that authenticate to arbitrary databases via the dbhost parameter.

The BulletProof Security WordPress plugin is vulnerable to sensitive information disclosure due to a file path disclosure in the publicly accessible ~/db_backup_log.txt file which grants attackers the full path of the site, in addition to the path of database backup files. This affects versions up to, and including, 5.1.

The BulletProof Security WordPress plugin before 6.1 does not sanitize and escape some of its CAPTCHA settings, which could allow high-privileged users to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed
