What the vulnerability does
The Ocean Extra plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's oceanwp_library shortcode in all versions up to, and including, 2.4.9 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
Ocean Extra versions up to 2.4.9 contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, including administrators. The vulnerability affects the entire site scope due to how the vulnerable component processes user input.
What an attacker can do
Inject malicious scripts that run in other users' browsers, potentially stealing session tokens or admin credentials.
Potential impact on your site
Authenticated users can compromise admin accounts and take control of your site without needing to exploit additional vulnerabilities.
Conditions required to exploit
Attacker must have a low-privilege account on the site (e.g., subscriber or contributor role).
