What the vulnerability does
The WP Event Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wp_events' shortcode in all versions up to, and including, 1.8.7 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
WP Event Aggregator versions up to 1.8.7 contain a cross-site scripting vulnerability that allows authenticated users to inject malicious scripts. The vulnerability affects the plugin's event import and display functionality. An attacker with low-level WordPress access can inject code that executes in other users' browsers, potentially compromising site security and user data.
What an attacker can do
Inject malicious JavaScript that runs in other users' browsers when they view affected pages.
Potential impact on your site
Authenticated attackers can steal admin credentials, modify site content, or redirect users to malicious sites.
Conditions required to exploit
Attacker must have a low-privilege WordPress account (e.g., contributor or subscriber role).
