CVE-2024-9233 is a medium-severity vulnerability classified as CWE-352 (Cross-Site Request Forgery) affecting the WordPress plugin 'Logo Slider' in versions prior to 3.7.1. The vulnerability arises because the plugin lacks proper CSRF protections when updating its settings. This means that an attacker can craft a malicious web request that, if executed by a logged-in WordPress administrator, could change the plugin's configuration without the administrator's consent or knowledge. The attack vector requires the victim to be authenticated as an admin and to interact with a malicious site or link that triggers the unauthorized request. The CVSS 3.1 base score is 4.3, reflecting a medium impact primarily on integrity, with no impact on confidentiality or availability. The attack complexity is low, no privileges are required beyond being logged in as an admin, and user interaction is necessary. There are no known exploits in the wild at this time, and no official patches or updates have been linked yet. The vulnerability was reserved in late September 2024 and published in May 2025. Given that WordPress is widely used for website management, and plugins like Logo Slider are common for displaying client logos or partner brands, this vulnerability could be exploited to alter website content or behavior surreptitiously, potentially damaging reputation or enabling further attacks through manipulated plugin settings.

For European organizations, the impact of this vulnerability depends on the presence of the Logo Slider plugin on their WordPress sites and the administrative practices in place. If exploited, attackers could modify plugin settings, potentially altering website appearance or functionality, which could undermine trust in the organization's web presence. While the vulnerability does not directly compromise data confidentiality or availability, integrity loss could facilitate phishing, misinformation, or indirect attacks by embedding malicious content or links. Organizations with public-facing websites relying on WordPress and this plugin are at risk, especially those with high visitor traffic or critical brand reputation. The requirement for an authenticated admin user limits the attack surface but does not eliminate risk, especially if administrators are targeted via social engineering or session hijacking. In sectors such as finance, healthcare, or government within Europe, where website integrity is crucial, this vulnerability could have reputational and operational consequences. Additionally, compliance with GDPR and other regulations may be impacted if website integrity issues lead to data misuse or loss of user trust.

European organizations should immediately audit their WordPress installations to identify the presence of the Logo Slider plugin and verify its version. If the plugin is installed and is a version prior to 3.7.1, organizations should prioritize updating to the latest version once available. In the absence of an official patch, temporary mitigations include restricting administrative access to trusted networks or VPNs, enforcing strong multi-factor authentication (MFA) for all admin accounts to reduce the risk of session hijacking, and educating administrators about the risks of CSRF and phishing attacks. Implementing Web Application Firewalls (WAFs) with rules to detect and block CSRF attempts targeting plugin settings endpoints can provide additional protection. Furthermore, organizations should review and harden WordPress security configurations, including limiting plugin usage to only those necessary and regularly monitoring admin activity logs for suspicious changes. Finally, website owners can implement Content Security Policy (CSP) headers to reduce the risk of malicious cross-site requests.
