What the vulnerability does
The WPGancio plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'gancio-event' shortcode in all versions up to, and including, 1.12 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
WPGancio versions 1.12 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has scope change, meaning injected code can affect other users or site functionality beyond the vulnerable component. An attacker with low-level site access can craft payloads that execute in other users' browsers, potentially compromising accounts or stealing data.
What an attacker can do
Inject malicious scripts that execute in other users' browsers, potentially stealing credentials or session tokens.
Potential impact on your site
Authenticated users with low privileges can compromise other users' accounts or modify site content via injected scripts.
Conditions required to exploit
Attacker must have low-level authenticated access to the site (e.g., subscriber or contributor role).
