CVE-2025-54705 is a Missing Authorization vulnerability (CWE-862) found in the magepeopleteam WpEvently WordPress plugin, affecting versions up to 4.4.6. This vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (requiring at least some level of authentication) to perform actions or access resources that should be restricted. The vulnerability does not require user interaction and can be exploited remotely over the network (AV:N), with low attack complexity (AC:L). The CVSS 3.1 base score is 4.3, indicating a medium severity level. The impact primarily affects availability (A:L), meaning that exploitation could lead to denial of service or disruption of plugin functionality, but does not compromise confidentiality or integrity. No known exploits are currently in the wild, and no patches have been linked yet. The vulnerability is significant because WordPress plugins like WpEvently are widely used for event management on websites, and improper authorization can lead to unauthorized actions that disrupt service or functionality. Since the vulnerability requires at least some privileges (PR:L), it is not exploitable by unauthenticated attackers, but any authenticated user with limited access could potentially exploit it. This increases the risk in environments where multiple users have accounts with varying privileges, such as multi-author blogs or organizational websites. The lack of user interaction requirement means exploitation can be automated once access is obtained. Overall, this vulnerability highlights the importance of strict access control enforcement in WordPress plugins to prevent privilege escalation or unauthorized operations.

For European organizations using the WpEvently plugin, this vulnerability could lead to service disruption or denial of event management functionalities on their websites. This can affect business continuity, customer engagement, and event-related operations, especially for organizations relying on online event scheduling and management. Although confidentiality and integrity are not directly impacted, availability issues can cause reputational damage and operational delays. Organizations with multiple authenticated users or contributors on their WordPress sites are at higher risk, as any user with limited privileges could exploit the flaw. This is particularly relevant for educational institutions, cultural organizations, and SMEs in Europe that use WordPress for event management. The medium severity score suggests the threat is moderate but should not be ignored, especially since no patches are currently available. The absence of known exploits in the wild provides some window for mitigation, but proactive measures are necessary to prevent potential exploitation.

1. Immediately review and restrict user privileges on WordPress sites using WpEvently, ensuring that only trusted users have authenticated access. 2. Monitor user activity logs for unusual or unauthorized actions related to event management features. 3. Temporarily disable or uninstall the WpEvently plugin if event management is not critical or if no immediate patch is available. 4. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting WpEvently endpoints. 5. Follow magepeopleteam and WordPress plugin repositories closely for official patches or updates addressing this vulnerability and apply them promptly. 6. Conduct internal security audits focusing on access control configurations within WordPress and its plugins to identify and remediate similar authorization issues. 7. Educate site administrators and users about the risks of privilege misuse and enforce strong authentication and role management policies.
