What the vulnerability does
The WP Data Access plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wpda_app' shortcode in all versions up to, and including, 5.5.63 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 Data Access contains a cross-site scripting (XSS) vulnerability in versions up to 5.5.63. An authenticated user with low privileges can inject malicious scripts that execute in other users' browsers, potentially compromising their sessions or stealing data. The vulnerability affects the entire site scope due to how the plugin processes user input.
What an attacker can do
Inject JavaScript that runs in other users' browsers and steals their session data or perform actions on their behalf.
Potential impact on your site
Authenticated users' accounts and data are at risk; attackers can hijack admin sessions or modify site content.
Conditions required to exploit
Attacker must have a low-privilege WordPress account (e.g., subscriber or contributor role).
