Description
WordPress Plugin Event Registration is prone to an SQL injection vulnerability because it fails to sufficiently sanitize user-supplied data before using it in an SQL query. Exploiting this issue could allow an attacker to compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. Successful exploitation requires that "magic_quotes" directive is set to "Off". WordPress Plugin Event Registration version 5.43 is vulnerable; other versions may also be affected.
Remediation
