CVE-2025-49966 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Oganro Travel Portal Search Widget, which integrates with the HotelBeds APITUDE API. This vulnerability affects versions up to 1.0 of the widget. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a malicious request to a web application without their consent or knowledge. In this case, the vulnerability allows an attacker to perform unauthorized actions on behalf of a user by exploiting the trust that the application places in the user's browser. The vulnerability does not impact confidentiality or availability directly but can lead to integrity issues by enabling unauthorized state-changing requests. The CVSS 3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The attack complexity is low (AC:L), and the scope is unchanged (S:U). The vulnerability does not affect confidentiality (C:N) or availability (A:N) but impacts integrity to a low degree (I:L). There are no known exploits in the wild, and no patches have been published at the time of analysis. The vulnerability is categorized under CWE-352, which is a common web security weakness related to CSRF attacks. The widget is used to facilitate hotel searches via the HotelBeds APITUDE API, which is a widely used travel industry API for booking and inventory management. The vulnerability could allow attackers to manipulate search parameters or booking requests if the user is authenticated and visits a malicious site, potentially leading to unauthorized actions or data manipulation within the travel portal context.

For European organizations, particularly those in the travel and hospitality sectors using the Oganro Travel Portal Search Widget integrated with HotelBeds APITUDE API, this vulnerability could lead to unauthorized manipulation of booking or search requests. While the direct impact on confidentiality and availability is minimal, the integrity of booking data and user actions can be compromised. This could result in fraudulent bookings, altered search results, or unauthorized changes to user preferences or session data. Such integrity breaches may damage customer trust, lead to financial discrepancies, and complicate reconciliation processes. Additionally, if attackers exploit this vulnerability at scale, it could disrupt normal business operations and customer experience. Given the reliance on online travel portals in Europe and the importance of accurate booking data, the vulnerability poses a moderate risk. However, the requirement for user interaction and the absence of privilege requirements limit the attack surface somewhat. Organizations with high volumes of online bookings and integrations with HotelBeds API are more at risk. The lack of known exploits reduces immediate threat but does not eliminate future risk, especially as attackers often target web widgets and APIs in the travel sector.

To mitigate this CSRF vulnerability effectively, European organizations should implement the following specific measures: 1) Employ anti-CSRF tokens: Ensure that the Oganro Travel Portal Search Widget includes unique, unpredictable CSRF tokens in all state-changing requests, validated server-side. 2) Use SameSite cookies: Configure authentication cookies with the 'SameSite' attribute set to 'Strict' or 'Lax' to prevent cross-origin requests from including cookies. 3) Validate HTTP Referer and Origin headers: Implement strict server-side checks to confirm that requests originate from trusted domains. 4) Update or patch the widget: Monitor Oganro vendor communications for patches or updated versions addressing this vulnerability and apply them promptly. 5) Limit user privileges: Where possible, restrict the scope of actions that can be performed without additional authentication or confirmation. 6) Educate users: Inform users about the risks of clicking on untrusted links while authenticated to the travel portal. 7) Implement Content Security Policy (CSP): Use CSP headers to restrict the domains that can execute scripts or send requests to the widget. 8) Monitor logs for unusual activity: Detect patterns indicative of CSRF exploitation attempts, such as unexpected state changes or repeated requests from unusual sources. These targeted mitigations go beyond generic advice by focusing on widget-specific controls and user interaction factors.
