CVE-2025-57892 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'Simple Statistics for Feeds' developed by Jeff Starr. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged HTTP request, typically exploiting the user's active session to perform unwanted actions on a web application. In this case, the vulnerability affects all versions of the Simple Statistics for Feeds plugin up to and including the version released on 2025-03-22. The vulnerability allows an attacker to induce a logged-in user, such as an administrator or editor, to execute unintended actions without their consent by leveraging the user's credentials and session context. The CVSS v3.1 base score of 4.3 (medium severity) reflects that the attack vector is network-based (remote), requires no privileges, but does require user interaction (the victim must visit a malicious site or click a crafted link). The impact is limited to integrity, meaning the attacker can manipulate or alter data or settings within the plugin's scope but cannot directly affect confidentiality or availability. No known exploits are currently reported in the wild, and no patches or fixes have been published at the time of this report. The vulnerability is categorized under CWE-352, which is a common web security weakness related to insufficient request validation and lack of anti-CSRF tokens or mechanisms. Given the plugin's function—providing statistics for RSS feeds—an attacker could potentially alter statistical data or plugin settings, which might mislead site administrators or affect site analytics.

For European organizations, the impact of this CSRF vulnerability depends largely on the usage of the Simple Statistics for Feeds plugin within their WordPress environments. Organizations relying on this plugin for feed analytics could face data integrity issues, where attackers manipulate statistics or plugin configurations, potentially leading to incorrect business decisions or misinformed content strategies. While the vulnerability does not directly compromise sensitive data confidentiality or site availability, the manipulation of statistics could indirectly affect trustworthiness and operational insights. Additionally, if the plugin is used by administrators with elevated privileges, attackers might leverage this to perform further unauthorized actions within the WordPress site, escalating the impact. Given the medium severity and the requirement for user interaction, the threat is moderate but should not be underestimated, especially for organizations with public-facing WordPress sites that use this plugin. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation.

To mitigate this vulnerability, European organizations should first verify whether the Simple Statistics for Feeds plugin is installed and active on their WordPress sites. If so, immediate steps include: 1) Restricting administrative access and ensuring that users with high privileges are trained to avoid clicking on suspicious links or visiting untrusted websites. 2) Implementing Web Application Firewalls (WAFs) that can detect and block CSRF attack patterns or suspicious HTTP requests targeting the plugin's endpoints. 3) Monitoring and logging plugin-related activities to detect unusual changes in statistics or settings. 4) Applying any available patches or updates from the plugin vendor as soon as they are released; if no patch is available, consider temporarily disabling the plugin or replacing it with alternative solutions that have robust CSRF protections. 5) Employing security plugins or custom code to add CSRF tokens and nonce verification to plugin actions if feasible. 6) Conducting regular security audits and penetration testing focused on WordPress plugins to identify and remediate similar vulnerabilities proactively.
