The vulnerability identified as CVE-2025-69352 affects StellarWP's The Events Calendar plugin, a popular WordPress extension used for event management. The core issue is a missing authorization control, meaning that certain actions within the plugin do not properly verify whether the user has the necessary permissions to perform them. This misconfiguration in access control security levels can be exploited by attackers to execute unauthorized operations, potentially including viewing, modifying, or deleting event data or altering plugin settings. The affected versions include all releases up to and including 6.15.12.2. The vulnerability was reserved at the end of 2025 and published in early 2026, with no CVSS score assigned yet and no known exploits reported in the wild. The lack of patch links suggests that a fix may still be pending or in development. The missing authorization flaw is critical because it undermines the fundamental security principle of least privilege, allowing attackers to escalate privileges or access sensitive information without proper authentication or authorization checks. Since The Events Calendar is widely used across many WordPress sites, the attack surface is broad, especially for organizations relying on this plugin for managing public or internal events. Exploitation likely requires no user interaction or complex conditions, increasing the risk profile. The vulnerability's technical details emphasize incorrect access control configurations, a common and impactful security weakness in web applications and plugins.

For European organizations, the impact of CVE-2025-69352 could be significant, particularly for those relying on The Events Calendar plugin for managing event-related data and workflows. Unauthorized access or modification of event information could lead to data breaches, disruption of event operations, and reputational damage. Confidentiality may be compromised if sensitive event details or user information are exposed. Integrity risks arise if attackers alter event data, potentially causing misinformation or operational failures. Availability might be indirectly affected if attackers disrupt event management processes or cause plugin malfunctions. Given the plugin's integration with WordPress, a widely used CMS in Europe, the vulnerability could affect a large number of organizations, including businesses, educational institutions, and government entities. The absence of authentication requirements for exploitation increases the threat level, making it easier for remote attackers to leverage the flaw. This could also facilitate lateral movement within compromised networks if attackers gain elevated privileges. The lack of known exploits currently reduces immediate risk but does not eliminate the potential for future attacks, especially once exploit code becomes publicly available.

Organizations should immediately inventory their WordPress installations to identify the use of The Events Calendar plugin and verify the version in use. Until an official patch is released, administrators should restrict access to the plugin's management interfaces by limiting user roles and permissions to only trusted personnel. Implementing web application firewall (WAF) rules to detect and block suspicious requests targeting the plugin's endpoints can provide temporary protection. Monitoring logs for unusual access patterns or unauthorized attempts to manipulate event data is critical for early detection. Organizations should subscribe to vendor advisories and security mailing lists to receive timely updates about patches or mitigations. Additionally, conducting a thorough review of user roles and capabilities in WordPress can help minimize the risk of privilege escalation. Where possible, isolating the WordPress environment and employing network segmentation can reduce the impact of a potential compromise. Finally, preparing an incident response plan specific to web application vulnerabilities will enhance readiness for any exploitation attempts.
