CVE-2025-47565 is a medium severity vulnerability classified under CWE-862 (Missing Authorization) affecting the EventON plugin developed by ashanjay, specifically versions up to 4.9.9. This vulnerability arises due to improperly configured access control mechanisms within the EventON plugin, which is commonly used for event management on WordPress websites. The flaw allows an attacker with at least limited privileges (PR:L - privileges required: low) to bypass authorization checks and perform actions or access data beyond their intended permissions. The CVSS 3.1 base score is 6.3, reflecting a network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and an unchanged scope (S:U). The impact affects confidentiality, integrity, and availability at a low level (C:L/I:L/A:L), meaning that while the attacker can gain unauthorized access or modify data, the damage is somewhat limited in scale or severity. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that the vulnerability is newly disclosed and may require immediate attention from users of the affected plugin. The vulnerability could be exploited remotely over the network without user interaction, but requires the attacker to have some level of authenticated access, such as a low-privilege user account. This scenario is typical in multi-user WordPress environments where contributors or subscribers might escalate privileges or access restricted event data or administrative functions improperly protected by the plugin's authorization logic.

For European organizations using WordPress sites with the EventON plugin, this vulnerability poses a risk of unauthorized data exposure, modification of event information, or disruption of event management functionalities. Organizations relying on EventON for critical event scheduling, ticketing, or internal communications could face data integrity issues or leakage of sensitive event details. Given the low privilege requirement, insider threats or compromised low-level accounts could be leveraged to exploit this vulnerability. This could lead to reputational damage, especially for organizations handling personal data under GDPR, as unauthorized access could constitute a data breach. Additionally, attackers might use this vulnerability as a foothold to escalate privileges or pivot to other parts of the network, increasing the risk of broader compromise. The absence of known exploits currently reduces immediate risk, but the availability of the vulnerability details and lack of patches necessitate proactive mitigation to prevent exploitation.

European organizations should immediately audit their WordPress installations to identify the presence and version of the EventON plugin. Until an official patch is released, it is recommended to restrict access to EventON functionalities by limiting user roles and permissions, ensuring that only trusted users have accounts with access to event management features. Implementing web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting EventON endpoints can provide an additional layer of defense. Monitoring logs for unusual activity related to EventON, such as unexpected API calls or privilege escalations, is critical. Organizations should also consider temporarily disabling or removing the EventON plugin if it is not essential or if the risk outweighs the benefit. Regularly checking for vendor updates or security advisories from ashanjay and applying patches promptly once available is essential. Finally, enforcing strong authentication mechanisms and conducting user access reviews can reduce the risk posed by low-privilege attackers.
