CVE-2025-62651 is a vulnerability classified under CWE-863 (Incorrect Authorization) found in the Restaurant Brands International assistant platform. The issue lies in the lack of proper access control enforcement on the bathroom rating interface, allowing any remote attacker to interact with this interface without authentication or user interaction. This means that unauthorized users can potentially view or modify bathroom ratings, which could lead to data integrity issues or unauthorized information disclosure. The vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), making it relatively easy to exploit. The scope is unchanged (S:U), and the impact affects confidentiality and integrity at a low level (C:L/I:L) but does not affect availability (A:N). Although the vulnerability does not directly impact critical business functions or availability, it undermines trust in the platform’s data and could be leveraged for further attacks or reputational damage. No patches or known exploits are currently available, indicating that this is a newly disclosed vulnerability requiring attention from RBI and its customers. The assistant platform is likely used in RBI’s restaurant operations, and unauthorized access to internal rating systems could expose sensitive operational data or allow manipulation of customer feedback mechanisms.

For European organizations using the RBI assistant platform, this vulnerability could lead to unauthorized access and manipulation of internal rating data, potentially affecting operational decision-making and customer trust. While the direct impact on confidentiality and integrity is low, the ability to alter ratings without authorization could be exploited for reputational harm or to mask other malicious activities. This could be particularly impactful in countries where RBI brands have a strong market presence, as attackers might leverage this vulnerability to influence customer perceptions or disrupt internal quality controls. Additionally, the lack of authentication could serve as an entry point for more sophisticated attacks if combined with other vulnerabilities. The absence of availability impact means service disruption is unlikely, but data integrity and confidentiality concerns remain relevant. Organizations may face compliance risks if personal or sensitive data is indirectly exposed through this interface.

Organizations should immediately review and enforce strict access control policies on the bathroom rating interface within the RBI assistant platform. This includes implementing authentication and authorization checks to ensure only authorized personnel can access or modify rating data. Network-level controls such as segmentation and firewall rules should restrict access to the platform’s management interfaces. Monitoring and logging access attempts to the bathroom rating interface should be enabled to detect unauthorized activities promptly. RBI should prioritize developing and releasing a patch to address this authorization flaw. Until a patch is available, organizations could consider disabling or restricting access to the affected interface if feasible. Security teams should also conduct thorough audits of the platform’s access control mechanisms to identify and remediate similar weaknesses. Employee training on recognizing suspicious activity related to platform misuse can further reduce risk.
