WordPress Plugin Vulnerabilities

Contest Gallery < 19.1.5 - Admin+ SQL Injection

Description

The plugins do not escape the cg_option_id POST parameter before concatenating it to an SQL query in export-votes-all.php. This may allow malicious users with administrator privileges (i.e. on multisite WordPress configurations) to leak sensitive information from the site's database.

Proof of Concept
