CVE-2020-37151Public exploitNetwork attack vector

Database disclosure via deluser.php username injection

Published Feb 5, 2026 · Updated Feb 5, 2026

SQL injection in phpMyChat-Plus 1.98 allows remote attackers to read sensitive database data through a crafted username. The deluser.php request path places the pmc_username value into a database query without neutralizing SQL syntax, enabling boolean-, error-, and time-based extraction. No authentication or user interaction is required, and the demonstrated consequence is disclosure of database contents rather than service interruption.
