CVE-2024-8369 is a vulnerability identified in the EventPrime – Events Calendar, Bookings and Tickets plugin for WordPress, developed by metagauss. The issue stems from missing authorization checks in all versions up to 4.0.4.3, which means that private or password-protected events can be accessed by unauthenticated attackers. This vulnerability is classified as CWE-862, indicating a failure to enforce proper authorization controls. The vulnerability allows attackers to bypass intended access restrictions and view sensitive event details that should be protected. The CVSS 3.1 base score is 5.3, reflecting a medium severity level, with an attack vector of network (remote), low attack complexity, no privileges required, and no user interaction needed. The scope remains unchanged, and the impact is limited to confidentiality loss, with no impact on integrity or availability. No known exploits have been reported in the wild, and no patches have been officially released at the time of this analysis. The vulnerability poses a risk primarily to organizations that rely on EventPrime for managing private or password-protected events, potentially exposing sensitive event information to unauthorized parties. The lack of authorization checks indicates a design or implementation flaw in the plugin's access control mechanisms, which should be addressed by the vendor promptly.

The primary impact of CVE-2024-8369 is unauthorized disclosure of private or password-protected event information, which can lead to privacy violations and potential reputational damage for organizations. Sensitive event details, such as attendee lists, event schedules, or confidential booking information, may be exposed to the public or malicious actors. While the vulnerability does not affect data integrity or system availability, the confidentiality breach can undermine trust in the affected organizations and may have legal or compliance implications, especially where personal data is involved. Attackers do not require authentication or user interaction, making exploitation straightforward once the vulnerability is known. Organizations using this plugin for internal or sensitive events are at particular risk. Although no active exploitation has been reported, the public disclosure increases the likelihood of future attacks. The impact is more significant for entities that rely heavily on private event management, such as corporate event planners, educational institutions, or membership-based organizations.

Until an official patch is released by metagauss, organizations should implement compensating controls to mitigate the risk. These include restricting access to the WordPress site or the EventPrime plugin pages via IP whitelisting or VPN access to trusted users only. Administrators can also consider disabling or uninstalling the EventPrime plugin if private event confidentiality is critical and no immediate fix is available. Reviewing and tightening WordPress user roles and permissions to limit exposure is recommended. Monitoring web server logs for unusual access patterns to event URLs can help detect exploitation attempts. Employing web application firewalls (WAFs) with custom rules to block unauthorized requests targeting EventPrime endpoints may reduce risk. Organizations should subscribe to vendor advisories and security mailing lists to promptly apply patches once available. Additionally, educating event organizers about the risk and encouraging use of alternative secure communication channels for sensitive event details can reduce exposure. Regular security audits of WordPress plugins and configurations are advised to identify and remediate similar issues proactively.
