CVE-2025-22670 identifies a Missing Authorization vulnerability in the VikBooking Hotel Booking Engine & PMS developed by e4jvikwp, affecting all versions up to and including 1.7.2. The vulnerability arises from improperly configured access control security levels, which fail to enforce authorization checks on certain operations or endpoints within the booking engine and property management system. This misconfiguration allows an attacker to bypass intended restrictions and perform unauthorized actions, potentially including viewing, modifying, or deleting booking data, managing reservations, or altering system configurations. The vulnerability does not require user interaction, and exploitation is possible remotely if the attacker can access the vulnerable interface. No public exploits have been reported yet, but the flaw represents a significant risk due to the sensitive nature of hotel booking and PMS data, which often includes personal customer information and payment details. The lack of a CVSS score means severity must be inferred from the impact on confidentiality, integrity, and availability, as well as ease of exploitation. The vulnerability affects hospitality organizations using VikBooking, which is a niche but globally used hotel management solution. The vendor has not yet released a patch, so mitigation relies on access restrictions and monitoring.

The impact of CVE-2025-22670 is substantial for organizations using VikBooking Hotel Booking Engine & PMS. Unauthorized access could lead to exposure or manipulation of sensitive customer data, including personal identification and payment information, resulting in privacy breaches and potential financial fraud. Integrity of booking records and hotel management operations could be compromised, causing operational disruptions and loss of trust. Attackers might alter reservations, cancel bookings, or manipulate pricing and availability, directly affecting revenue and customer satisfaction. The vulnerability could also serve as a foothold for further attacks within the hotel’s IT infrastructure. Given the hospitality sector’s reliance on continuous availability and data confidentiality, this vulnerability poses risks to business continuity and regulatory compliance, especially under data protection laws like GDPR. The absence of known exploits reduces immediate risk but does not diminish the potential severity if exploited.

To mitigate CVE-2025-22670, organizations should immediately restrict access to the VikBooking administrative and management interfaces using network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure to trusted personnel only. Implement strong authentication and session management policies to reduce unauthorized access risk. Monitor logs and system activity for unusual access patterns or unauthorized operations. Until an official patch is released by e4jvikwp, consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting access control weaknesses. Conduct a thorough review of user roles and permissions within VikBooking to ensure the principle of least privilege is enforced. Engage with the vendor for updates and apply patches promptly once available. Additionally, perform regular security assessments and penetration testing focused on access control mechanisms to identify and remediate similar issues proactively.
