CVE-2024-11432 is a stored cross-site scripting (XSS) vulnerability identified in the SuevaFree Essential Kit plugin for WordPress, a popular content management system. The vulnerability exists due to improper neutralization of input during web page generation, specifically within the 'counter' shortcode functionality. This flaw allows authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript code into pages by exploiting insufficient input sanitization and lack of proper output escaping on user-supplied shortcode attributes. When other users visit these compromised pages, the injected scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or unauthorized actions performed on behalf of the victim. The vulnerability affects all versions up to and including 1.1.3 of the plugin. The CVSS v3.1 base score is 6.4, reflecting a medium severity with network attack vector, low attack complexity, requiring privileges, no user interaction, and a scope change. Although no known exploits have been reported in the wild, the vulnerability poses a significant risk due to the common use of WordPress and the plugin’s functionality. The issue is classified under CWE-79, which covers improper neutralization of input leading to XSS. The vulnerability’s exploitation does not impact availability but can compromise confidentiality and integrity of user sessions and data. The absence of a patch link suggests that users should monitor vendor updates or apply manual mitigations.

The primary impact of CVE-2024-11432 is the compromise of confidentiality and integrity within affected WordPress sites. Exploitation allows attackers with contributor-level access to inject malicious scripts that execute in the browsers of site visitors or administrators, potentially leading to session hijacking, theft of sensitive information such as cookies or credentials, unauthorized actions performed with victim privileges, and defacement or manipulation of site content. While availability is not directly affected, the reputational damage and loss of user trust can be significant. Organizations relying on the SuevaFree Essential Kit plugin are at risk of targeted attacks, especially if they allow contributor-level users or have weak access controls. The vulnerability could also facilitate lateral movement within compromised environments or be leveraged as part of broader attack chains. Given WordPress’s widespread use globally, the threat surface is substantial, particularly for websites that do not promptly update or mitigate vulnerable plugins.

Organizations should immediately audit their WordPress installations for the presence of the SuevaFree Essential Kit plugin and verify the version in use. If running version 1.1.3 or earlier, they should upgrade to a patched version once available from the vendor. In the absence of an official patch, administrators should consider disabling or removing the plugin to eliminate the attack vector. Restrict contributor-level permissions to trusted users only and review user roles to minimize exposure. Implement web application firewalls (WAFs) with rules designed to detect and block malicious script injections targeting shortcode parameters. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. Regularly scan websites for XSS vulnerabilities and monitor logs for suspicious activity indicative of exploitation attempts. Educate content contributors about safe input practices and the risks of injecting untrusted content. Finally, maintain an incident response plan to quickly address any detected exploitation.
