CVE-2025-68547 identifies a missing authorization vulnerability (CWE-862) in the WPweb Follow My Blog Post WordPress plugin, affecting all versions up to 2.4.0. This vulnerability arises from improperly configured access control mechanisms that fail to verify whether a user is authorized to perform certain actions within the plugin. Specifically, the plugin exposes functionality that can be triggered remotely over the network without requiring any privileges or user interaction, allowing attackers to exploit the flaw directly. The impact vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The vulnerability does not compromise confidentiality or integrity but results in a high impact on availability (A:H), potentially causing denial of service conditions by disrupting the plugin’s normal operation or the hosting WordPress site’s functionality. Although no public exploits have been reported yet, the ease of exploitation and the critical nature of access control failures make this a significant threat. The absence of patches at the time of disclosure necessitates immediate mitigation efforts by administrators. The vulnerability is particularly relevant for organizations using this plugin to manage blog subscriptions or follow features, as attackers could disrupt these services, impacting user engagement and site reliability.

For European organizations, the primary impact of CVE-2025-68547 is the potential denial of service on WordPress sites utilizing the Follow My Blog Post plugin. This can lead to service outages, degraded user experience, and loss of trust from site visitors, especially for businesses relying on blog engagement for marketing or customer communication. The availability disruption could also affect internal communications if the plugin is used in intranet or private blog environments. Given the network-exploitable nature and no requirement for authentication, attackers can launch attacks from anywhere, increasing the risk of widespread disruption. Additionally, organizations may face reputational damage and potential compliance issues if service interruptions affect customer-facing platforms. The lack of known exploits currently provides a window for proactive defense, but the vulnerability’s characteristics suggest it could be targeted soon after disclosure. European entities with significant WordPress deployments, particularly in sectors like media, education, and e-commerce, are at heightened risk.

1. Immediately audit and restrict access controls related to the Follow My Blog Post plugin, ensuring that sensitive functions are not accessible to unauthenticated users. 2. If possible, disable or uninstall the Follow My Blog Post plugin until a security patch or update is released by WPweb. 3. Employ Web Application Firewalls (WAFs) to block suspicious requests targeting the plugin’s endpoints, especially those that appear to invoke follow or subscription functionalities without proper authorization. 4. Monitor web server and WordPress logs for unusual access patterns or repeated requests to the plugin’s features that could indicate exploitation attempts. 5. Implement network segmentation and limit exposure of WordPress administration interfaces to trusted IP addresses. 6. Stay informed about WPweb’s patch releases and apply updates promptly once available. 7. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect exploitation attempts of CWE-862 type vulnerabilities. 8. Educate site administrators about the risks of installing plugins without thorough security vetting and encourage regular security reviews of all third-party components.
