CyberRota Analysis

AI-Generated

The Contest Gallery plugin for WordPress is vulnerable to a second-order SQL injection due to inadequate escaping of the 'cgRealId' parameter in the 'cg_multiple_files_for_post' function. This flaw allows authenticated attackers with author-level access or higher to manipulate existing SQL queries, potentially leading to the extraction of sensitive database information. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of data exposure.
