CVE-2025-66082 identifies a missing authorization vulnerability in the magepeopleteam WpEvently WordPress plugin, specifically affecting versions up to and including 5.0.4. The root cause is an incorrectly configured access control mechanism that fails to properly verify whether a user is authorized to perform certain actions or access specific plugin functionalities. This allows unauthenticated remote attackers to interact with the plugin's features by sending crafted requests, potentially exposing sensitive information or triggering unintended behaviors. The vulnerability does not require authentication (PR:N) but does require some user interaction (UI:R), such as visiting a maliciously crafted URL. The attack vector is network-based (AV:N), meaning exploitation can occur remotely over the internet. The CVSS v3.1 base score is 4.3, reflecting a medium severity level primarily due to limited confidentiality impact and no impact on integrity or availability. No known public exploits or active exploitation campaigns have been reported to date. The vulnerability affects the mage-eventpress component of the plugin, which is commonly used for event management on WordPress sites, potentially exposing event-related data or administrative functions to unauthorized users. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for proactive mitigation.

For European organizations, the impact of CVE-2025-66082 is primarily related to the confidentiality of event-related data managed through the WpEvently plugin. Unauthorized access could lead to exposure of sensitive event details, attendee information, or internal scheduling data, which could be leveraged for social engineering or competitive intelligence. Although the vulnerability does not compromise data integrity or availability, the unauthorized disclosure of information can damage organizational reputation and trust, especially under GDPR regulations that mandate protection of personal data. Organizations relying heavily on WordPress for event management, particularly in sectors such as conferences, cultural events, and corporate meetings, may face increased risk. The absence of known exploits reduces immediate threat but does not eliminate the risk of future attacks. Attackers could exploit this vulnerability to gather intelligence or prepare for more sophisticated attacks. Additionally, the requirement for user interaction means phishing or social engineering campaigns could be used to lure victims into triggering the exploit.

1. Monitor for official patches or updates from magepeopleteam and apply them promptly once released. 2. In the interim, restrict access to WpEvently plugin endpoints using web application firewalls (WAFs) or reverse proxies to limit exposure to unauthenticated users. 3. Implement strict URL filtering and input validation rules to detect and block suspicious requests targeting the plugin. 4. Conduct regular audits of WordPress user roles and permissions to ensure minimal privileges are granted. 5. Educate users and administrators about phishing risks related to crafted URLs that could trigger the vulnerability. 6. Enable detailed logging and monitor web server logs for unusual access patterns or repeated attempts to access plugin-specific URLs. 7. Consider temporarily disabling the WpEvently plugin if event management functionality is not critical until a patch is available. 8. Employ network segmentation to isolate WordPress servers from sensitive internal systems to limit lateral movement in case of compromise.
