CVE-2025-49377 identifies a Missing Authorization vulnerability in the Themefic Hydra Booking plugin, affecting versions up to 1.1.9. The core issue stems from improperly configured access control mechanisms that fail to enforce authorization checks on certain functions or endpoints. This misconfiguration allows unauthenticated remote attackers to access sensitive data or perform actions that should be restricted. The vulnerability is exploitable over the network without requiring any privileges or user interaction, making it particularly dangerous. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), the attack vector is network-based with low attack complexity, no privileges or user interaction needed, and it impacts confidentiality at a high level, while integrity and availability remain unaffected. The flaw likely exposes sensitive booking information or user data managed by Hydra Booking, which could lead to privacy violations or data leakage. Although no public exploits have been reported yet, the vulnerability's characteristics suggest it could be weaponized by attackers targeting organizations that rely on this booking system. The absence of patches at the time of publication necessitates immediate attention to access control policies and monitoring for suspicious activity. Organizations should also prepare to deploy updates once available and consider temporary mitigations such as restricting access to vulnerable endpoints or deploying web application firewalls to detect and block unauthorized requests.

For European organizations, this vulnerability poses a significant risk of unauthorized data exposure, particularly for businesses in the service, hospitality, healthcare, and event management sectors that use Hydra Booking for scheduling and customer management. The confidentiality breach could lead to the disclosure of personally identifiable information (PII), booking details, and potentially sensitive operational data. This exposure can result in reputational damage, regulatory penalties under GDPR, and loss of customer trust. Since the vulnerability does not affect integrity or availability, the primary concern is data confidentiality. However, attackers could leverage the exposed information for further targeted attacks such as phishing or social engineering. The ease of exploitation without authentication increases the threat level, making European organizations attractive targets, especially those with high volumes of customer interactions and bookings. The lack of known exploits currently provides a window for proactive defense, but the risk of future exploitation remains high.

1. Monitor Themefic's official channels closely for patches addressing CVE-2025-49377 and apply them immediately upon release. 2. Conduct a thorough review of access control configurations within Hydra Booking to identify and remediate any improperly secured endpoints or functions. 3. Restrict network access to the booking system's administrative and sensitive endpoints using IP whitelisting or VPNs where feasible. 4. Deploy web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting Hydra Booking endpoints. 5. Implement robust logging and monitoring to detect unusual access patterns or unauthorized data retrieval attempts. 6. Educate IT and security teams about this vulnerability to ensure rapid response and incident handling. 7. If patching is delayed, consider temporarily disabling vulnerable features or restricting user roles to minimize exposure. 8. Review and enhance overall application security posture, including regular penetration testing focused on access control mechanisms.
