CVE-2025-9499

Vulnerability

Overview

The Ocean Extra plugin for WordPress (versions up to 2.4.9) contains a Stored Cross-Site Scripting (XSS) vulnerability in its oceanwp_library shortcode [1]. The flaw arises from insufficient input sanitization and output escaping on user-supplied attributes, allowing malicious script injection.

Exploitation

An authenticated attacker with contributor-level access or higher can inject arbitrary JavaScript code via the shortcode attributes. When a page containing the malicious shortcode is viewed by any user, the injected script executes in the browser, leading to Stored XSS.

Impact

Successful exploitation enables the attacker to execute arbitrary JavaScript in the context of the victim's session. This can result in session cookie theft, page defacement, redirection to malicious sites, or other actions that compromise the integrity and confidentiality of the WordPress site.

Mitigation

Users should update the Ocean Extra plugin to the latest available version, which contains a fix for this vulnerability. As the vulnerability requires contributor-level access, site administrators should also review user roles and permissions to limit exposure.
