CVE-2025-67597 identifies a Missing Authorization vulnerability in the Shahjahan Jewel Fluent Booking plugin, affecting all versions up to and including 1.9.11. The core issue stems from incorrectly configured access control security levels within the plugin, which can allow attackers to bypass authorization checks. This means that unauthorized users might perform actions or access data that should be restricted, potentially compromising the confidentiality and integrity of booking information. The vulnerability does not require prior authentication, increasing the risk of exploitation. Although no public exploits have been reported, the flaw's nature suggests that exploitation could be straightforward if attackers understand the plugin's internal access control logic. The plugin is commonly used in WordPress environments for managing bookings in hospitality, events, and similar sectors. The lack of a CVSS score means severity must be inferred from the vulnerability's characteristics: missing authorization typically leads to high-impact consequences, especially when it affects sensitive business operations. The vulnerability was published on December 9, 2025, by Patchstack, but no patches or fixes are currently linked, indicating that organizations must proactively assess and mitigate the risk. The vulnerability's exploitation could allow attackers to manipulate bookings, access personal customer data, or disrupt service availability, depending on the plugin's role and integration. Given the plugin's usage in customer-facing applications, the impact on business reputation and compliance with data protection regulations (such as GDPR) could be significant. The technical details emphasize the need for immediate attention to access control configurations and monitoring for suspicious activities within affected systems.

For European organizations, especially those in the hospitality, event management, and service booking sectors, this vulnerability poses a significant risk. Unauthorized access could lead to exposure or manipulation of sensitive customer data, including personal and payment information, which would violate GDPR requirements and potentially result in legal penalties and reputational damage. The integrity of booking records could be compromised, leading to operational disruptions, double bookings, or fraudulent reservations. Availability might also be affected if attackers exploit the vulnerability to disrupt booking processes. The absence of authentication requirements for exploitation increases the threat level, as external attackers could target vulnerable systems remotely. Organizations relying on Fluent Booking for critical customer interactions may face financial losses and customer trust erosion if the vulnerability is exploited. Additionally, the lack of patches at the time of disclosure means that organizations must rely on compensating controls, increasing the operational burden. The impact is heightened in countries with large tourism and hospitality industries, where booking systems are integral to business operations and customer experience.

1. Immediately audit and review all access control configurations within the Fluent Booking plugin to identify and correct any misconfigurations. 2. Monitor plugin vendor communications closely for the release of official patches or updates addressing CVE-2025-67597 and apply them promptly. 3. Implement compensating controls such as web application firewalls (WAFs) with rules designed to detect and block unauthorized access attempts targeting booking functionalities. 4. Restrict access to the booking management interfaces by IP whitelisting or VPN access where feasible to reduce exposure. 5. Conduct regular security assessments and penetration testing focused on access control mechanisms in the booking system. 6. Enhance logging and monitoring to detect anomalous activities indicative of exploitation attempts, including unusual booking modifications or access patterns. 7. Educate administrative users on the importance of access control hygiene and the risks associated with misconfigurations. 8. Consider isolating the booking system from other critical business systems to limit potential lateral movement in case of compromise. 9. Review and update incident response plans to include scenarios involving unauthorized access to booking systems. 10. Evaluate alternative booking solutions if timely patching or mitigation is not feasible, especially for high-risk environments.
