CVE-2025-62648 is an authorization vulnerability classified under CWE-863 found in the Restaurant Brands International assistant platform, which is used to manage various operational aspects including Drive Thru speaker systems. The vulnerability allows remote attackers who have some level of privileges (PR:L) to adjust the audio volume of Drive Thru speakers without proper authorization checks. The attack vector is network-based (AV:N) with low attack complexity (AC:L) and does not require user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially authorized scope. The impact on confidentiality is low (C:L) since the attacker gains no sensitive data, but availability is impacted (A:L) as attackers can disrupt normal Drive Thru operations by manipulating speaker volume, potentially causing communication issues with customers. Integrity is not affected (I:N). The vulnerability was published on October 17, 2025, with a CVSS v3.1 score of 6.4, indicating medium severity. No patches or known exploits are currently available. The root cause is improper authorization logic that fails to restrict volume adjustment commands to authorized personnel only. This flaw could be exploited to degrade service quality or cause operational confusion in Drive Thru environments, which are critical for quick service restaurants. The platform version affected is listed as '0', which likely indicates an initial or unspecified version. Given the operational nature of the vulnerability, it primarily threatens availability and service continuity rather than data confidentiality or integrity.

For European organizations operating RBI franchises, this vulnerability could lead to operational disruptions in Drive Thru services, which are a significant revenue channel. Attackers adjusting speaker volume could cause miscommunication with customers, leading to order errors, customer dissatisfaction, and potential loss of business. While the confidentiality impact is low, the availability impact could affect customer experience and brand reputation. In high-traffic locations, such disruptions could cause queues and delays, impacting overall service efficiency. Additionally, if attackers use this as a foothold, it could lead to further exploitation within the network. The lack of patches increases the risk window, and organizations relying heavily on the assistant platform must prioritize mitigation. The threat is more pronounced in countries with dense RBI franchise networks and high Drive Thru usage, where operational continuity is critical.

1. Implement strict role-based access controls (RBAC) to ensure only authorized personnel can adjust Drive Thru speaker settings. 2. Enforce network segmentation to isolate the assistant platform from broader corporate networks, limiting attack surface exposure. 3. Monitor and log all commands related to audio system adjustments to detect anomalous or unauthorized activities promptly. 4. Conduct regular security audits and penetration testing focusing on authorization mechanisms within the assistant platform. 5. Until patches are available, consider deploying compensating controls such as multi-factor authentication for access to the platform. 6. Engage with RBI vendor support to obtain timelines for patches or workarounds. 7. Train staff to recognize and report unusual Drive Thru behavior that could indicate exploitation. 8. Review and harden firewall and intrusion detection/prevention system (IDS/IPS) rules to detect and block unauthorized access attempts to the assistant platform.
