CVE-2025-68547 is a missing authorization vulnerability classified under CWE-862 that affects the WPweb Follow My Blog Post WordPress plugin, up to version 2.4.0. The vulnerability arises from incorrectly configured access control mechanisms that fail to properly restrict access to certain plugin functionalities. This allows unauthenticated remote attackers to exploit the plugin over the network without requiring any privileges or user interaction. The CVSS 3.1 base score of 7.5 reflects a high severity primarily due to the vulnerability's impact on availability (denial of service or disruption), while confidentiality and integrity remain unaffected. The vulnerability does not require authentication, making it easier to exploit. Although no public exploits have been reported yet, the potential for attackers to disrupt website availability is significant, especially for sites relying on this plugin for blog post following features. The lack of patch links indicates that a fix may not yet be publicly available, increasing the urgency for mitigation through alternative controls. The vulnerability's exploitation could lead to service interruptions, affecting user experience and potentially damaging organizational reputation. The technical details confirm the vulnerability was reserved in late 2025 and published in early 2026, indicating it is a recent discovery.

For European organizations, the primary impact of CVE-2025-68547 is the potential disruption of availability of WordPress sites using the Follow My Blog Post plugin. This can lead to denial of service conditions, affecting customer-facing websites, internal blogs, or content delivery platforms. Organizations relying on this plugin for user engagement or content distribution may experience outages, resulting in loss of user trust and potential revenue impact. While confidentiality and integrity are not directly compromised, availability issues can indirectly affect business continuity and operational efficiency. Given the plugin's role in social/blogging features, websites with high traffic or critical communication functions are at greater risk. The absence of authentication requirements means attackers can exploit the vulnerability at scale, potentially targeting multiple sites simultaneously. European entities with strict uptime requirements or regulatory obligations around service availability (e.g., e-commerce, media, government portals) may face compliance challenges if disruptions occur. The lack of known exploits currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits rapidly once details are public.

1. Monitor WPweb and official plugin channels closely for the release of an official patch and apply it immediately upon availability. 2. Until a patch is available, restrict access to the Follow My Blog Post plugin endpoints via web application firewalls (WAFs) or server-level access controls, limiting exposure to trusted IP addresses only. 3. Conduct thorough access control reviews on WordPress installations to ensure no unnecessary permissions are granted to anonymous users. 4. Implement network-level protections such as rate limiting and anomaly detection to identify and block suspicious traffic targeting the plugin. 5. Regularly scan WordPress environments with vulnerability assessment tools that include checks for missing authorization issues. 6. Educate site administrators on the risks of running outdated or unpatched plugins and enforce strict update policies. 7. Consider temporary disabling or removing the Follow My Blog Post plugin if it is not critical to operations until the vulnerability is resolved. 8. Maintain comprehensive backups and incident response plans to quickly recover from potential denial of service incidents.
