CVE-2020-8088: Usebb

Critical severity, CVSS 9.8. EPSS: 1.4% chance of exploitation in the next 30 days.

panel_login.php in UseBB 1.0.12 allows type juggling for login bypass because != is used instead of !== for password hashes, which mishandles hashes that begin with 0e followed by exclusively numerical characters.
