CVE-2025-48246 is a medium-severity vulnerability classified under CWE-862, which corresponds to Missing Authorization. This vulnerability affects The Events Calendar plugin, a widely used WordPress plugin for managing and displaying events. The flaw arises due to incorrectly configured access control security levels, allowing users with limited privileges (PR:L - privileges required: low) to perform actions that should be restricted. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N). The impact includes limited confidentiality impact (C:N), but it can lead to integrity (I:L) and availability (A:L) issues. Specifically, an attacker with low-level privileges could manipulate event data or disrupt event-related functionalities without proper authorization checks. The affected versions include all versions up to 6.11.2.1, with no specific version excluded. Although no known exploits are currently in the wild, the vulnerability is publicly disclosed and rated with a CVSS 3.1 score of 5.4, indicating a medium risk. The lack of a patch link suggests that a fix may not yet be available or publicly released. The vulnerability's root cause is an access control misconfiguration, which is a common security weakness that can lead to unauthorized actions within the application.

For European organizations, especially those relying on WordPress and The Events Calendar plugin to manage public or internal events, this vulnerability poses a risk of unauthorized modification or disruption of event data. This can lead to misinformation, event cancellations, or denial of service related to event management. Organizations in sectors such as education, government, cultural institutions, and event management companies are particularly at risk, as they often use such plugins to coordinate critical activities. The integrity and availability impacts could undermine trust in event communications and potentially disrupt business operations or public services. Additionally, unauthorized changes could be leveraged for social engineering or misinformation campaigns. Since the vulnerability requires only low-level privileges, attackers might exploit compromised or low-trust user accounts to escalate their impact.

European organizations should immediately audit their WordPress installations to identify if The Events Calendar plugin is in use and verify the version. Until a patch is available, administrators should restrict plugin access to trusted users only and review user roles and permissions to minimize the number of accounts with event management capabilities. Implementing strict role-based access control (RBAC) and monitoring for unusual activity related to event creation or modification is critical. Organizations should also consider temporarily disabling or removing the plugin if it is not essential. Web application firewalls (WAFs) can be configured to detect and block suspicious requests targeting event management endpoints. Regular backups of event data should be maintained to enable recovery in case of tampering. Finally, organizations should stay alert for official patches or updates from the vendor and apply them promptly once released.
