CVE-2025-47614 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Chris Clark LessButtons Social Sharing and Statistics plugin, versions up to and including 1.6.1. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application in which the user is currently authenticated, thereby performing unwanted actions on behalf of the user without their consent. In this case, the LessButtons plugin, which is used to add social sharing buttons and track statistics on websites, does not adequately verify the origin or authenticity of requests that trigger certain actions. This lack of proper anti-CSRF tokens or validation mechanisms allows remote attackers to craft malicious web pages or links that, when visited by an authenticated user of a site using this plugin, can cause unintended changes or actions within the plugin's functionality. The CVSS 3.1 base score of 4.3 (medium severity) reflects that the vulnerability requires no privileges (PR:N), can be exploited remotely over the network (AV:N), requires user interaction (UI:R), and impacts integrity (I:L) but not confidentiality or availability. There are no known exploits in the wild at the time of publication, and no patches have been linked yet. The vulnerability is categorized under CWE-352, which specifically relates to CSRF issues. Since the plugin is typically used in content management systems or websites to facilitate social sharing, the attack surface includes any web application that integrates this plugin and has authenticated users with sufficient privileges to perform actions that can be abused via CSRF. The lack of authentication requirements for exploitation means that any attacker can attempt to lure authenticated users into visiting malicious pages to trigger the exploit. However, the requirement for user interaction (clicking or visiting a malicious link) somewhat limits automated exploitation. Overall, this vulnerability poses a risk of unauthorized modification of plugin settings or statistics manipulation, potentially undermining the integrity of the website's social sharing features and data.

For European organizations, the impact of this CSRF vulnerability depends on the extent to which they use the Chris Clark LessButtons Social Sharing and Statistics plugin on their websites or web applications. Organizations relying on this plugin for social media integration and analytics may face risks of unauthorized changes to plugin configurations or falsified statistics, which could mislead marketing and decision-making processes. While the vulnerability does not directly compromise user data confidentiality or availability of services, the integrity impact could affect trustworthiness of social sharing metrics and potentially enable attackers to manipulate social signals or website behavior. This could have reputational consequences, especially for companies with strong online presence or e-commerce platforms. Additionally, if the plugin is used in environments where administrative actions can be triggered via the plugin interface, attackers might leverage CSRF to perform unauthorized administrative operations indirectly. European organizations subject to strict data protection regulations such as GDPR must also consider that any manipulation or unauthorized changes could lead to compliance issues if it results in inaccurate data reporting or affects user consent mechanisms. Given the medium severity and the need for user interaction, the threat is moderate but should not be ignored, especially for organizations with high web traffic and user engagement.

To mitigate this vulnerability, European organizations should take the following specific actions: 1) Immediately review whether their websites or applications use the Chris Clark LessButtons Social Sharing and Statistics plugin, particularly versions up to 1.6.1. 2) If the plugin is in use, restrict access to administrative or configuration interfaces to trusted users and consider disabling the plugin temporarily until a patch or update is available. 3) Implement or verify the presence of anti-CSRF tokens on all state-changing requests related to the plugin, ensuring that the server validates these tokens properly. 4) Educate users and administrators about the risks of clicking on suspicious links or visiting untrusted websites while authenticated to sensitive web applications. 5) Monitor web server logs and application behavior for unusual or unauthorized requests that could indicate attempted exploitation. 6) Follow vendor communications closely for any released patches or updates addressing this vulnerability and apply them promptly. 7) Employ web application firewalls (WAFs) with rules designed to detect and block CSRF attack patterns targeting the plugin endpoints. 8) Conduct security testing and code reviews of the plugin integration to identify and remediate any additional weaknesses related to request validation and user session management. These targeted measures go beyond generic advice by focusing on the specific plugin and its usage context.
