CVE-2025-47565 is a Missing Authorization vulnerability (CWE-862) found in the ashanjay EventON product, affecting versions up to 4.9.9. This vulnerability arises from incorrectly configured access control security levels, allowing an attacker with some level of privileges (PR:L - low privileges) to perform unauthorized actions without requiring user interaction (UI:N). The CVSS 3.1 base score is 6.3, indicating a medium severity level. The attack vector is network-based (AV:N), meaning exploitation can be performed remotely. The vulnerability impacts confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L), implying that an attacker can potentially access or modify data and disrupt service but not completely compromise the system. Since the vulnerability is due to missing authorization checks, it allows users with limited privileges to escalate their capabilities or access restricted functionalities or data that should otherwise be protected. No known exploits are currently reported in the wild, and no patches have been linked yet, which suggests that the vulnerability is either newly disclosed or under active investigation. The vulnerability affects EventON, a popular WordPress event calendar plugin developed by ashanjay, widely used for managing event listings and calendars on websites. The missing authorization could allow attackers to manipulate event data, access sensitive event information, or disrupt event management functionalities, potentially impacting the reliability and trustworthiness of affected websites.

For European organizations, especially those relying on EventON for event management on their websites, this vulnerability poses a risk of unauthorized data access and modification. This could lead to leakage of sensitive event information, manipulation of event details, or denial of service on event-related functionalities, potentially damaging organizational reputation and user trust. Organizations in sectors such as education, government, cultural institutions, and event management companies that frequently use WordPress and EventON plugins are particularly at risk. The medium severity score indicates that while the vulnerability is not critical, it can still be leveraged to cause meaningful disruption or data compromise. Given the network-based attack vector and lack of required user interaction, exploitation could be automated or performed remotely, increasing the risk surface. The absence of known exploits in the wild currently reduces immediate threat but does not eliminate the risk of future exploitation. European organizations must consider the potential impact on confidentiality, integrity, and availability of their event management systems and associated data.

1. Immediate review and audit of access control configurations within EventON plugin settings to ensure proper authorization checks are enforced. 2. Restrict plugin access to only trusted users with necessary privileges and regularly review user roles and permissions. 3. Monitor EventON plugin updates and apply patches promptly once available from the vendor or security community. 4. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting EventON endpoints. 5. Conduct regular security assessments and penetration testing focusing on WordPress plugins, including EventON, to identify and remediate authorization weaknesses. 6. Employ logging and monitoring of event-related activities to detect unauthorized access or modifications early. 7. Consider isolating EventON functionalities or limiting exposure to public networks if feasible, reducing the attack surface. 8. Educate site administrators about the risks of privilege escalation and the importance of strict access controls within WordPress environments.
