CVE-2024-1570 is a stored cross-site scripting (XSS) vulnerability identified in the ProfilePress WordPress plugin, which encompasses Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile, and Restrict Content functionalities. The vulnerability specifically resides in the plugin's login-password shortcode, which fails to properly sanitize and escape user-supplied input attributes before rendering them in web pages. This flaw allows authenticated attackers with contributor-level or higher privileges to inject arbitrary JavaScript code that is persistently stored and executed in the context of any user who visits the affected page. The vulnerability stems from improper neutralization of script-related HTML tags (CWE-80), enabling injection of malicious scripts that can hijack user sessions, steal cookies, manipulate page content, or perform unauthorized actions on behalf of users. The attack vector is remote and network-based, requiring no user interaction beyond page access. The CVSS 3.1 score of 6.4 reflects a medium severity, with low attack complexity but requiring some level of authentication. No patches or fixes are linked yet, and no known exploits have been reported in the wild as of the publication date. The vulnerability affects all versions up to 4.14.4 inclusive, making it critical for administrators of WordPress sites using this plugin to assess exposure and implement mitigations promptly.

The impact of CVE-2024-1570 is significant for organizations using the affected ProfilePress plugin on WordPress sites. Exploitation allows authenticated users with contributor-level access or higher to inject persistent malicious scripts, which execute in the browsers of any visitors to the compromised pages. This can lead to session hijacking, theft of sensitive user data such as cookies or credentials, unauthorized actions performed with victim user privileges, and potential privilege escalation if administrative users are targeted. The vulnerability undermines the confidentiality and integrity of user data and site content, though it does not directly affect availability. Given the widespread use of WordPress and the popularity of membership and ecommerce plugins, many organizations including online retailers, membership sites, and community platforms could be at risk. Attackers could leverage this vulnerability to compromise user accounts, spread malware, or conduct phishing campaigns. The requirement for contributor-level authentication limits exposure somewhat but still poses a risk in environments where multiple users have such privileges or where accounts can be compromised. The lack of known exploits in the wild currently reduces immediate risk but does not preclude future exploitation.

To mitigate CVE-2024-1570, organizations should first verify if they are using the affected ProfilePress plugin versions (up to 4.14.4). If a patched version is released, immediate updating to the latest secure version is the best remediation. In the absence of an official patch, administrators should restrict contributor-level permissions to trusted users only and audit existing user roles to minimize risk. Implementing a Web Application Firewall (WAF) with rules to detect and block common XSS payloads targeting the login-password shortcode can provide temporary protection. Site owners should also enable Content Security Policy (CSP) headers to restrict script execution sources, reducing the impact of injected scripts. Regularly scanning the site for injected malicious scripts and monitoring logs for suspicious activity is advised. Developers maintaining the plugin should apply proper input validation and output encoding on all user-supplied attributes in shortcodes. Finally, educating users about the risks of XSS and maintaining strong authentication controls will help reduce exploitation likelihood.
