Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Immediate mitigation should focus on eliminating client-side authentication mechanisms for sensitive functions like the diagnostic screen. RBI and affected organizations should implement robust server-side authentication and authorization controls to ensure access is validated securely on the server. Network segmentation should be enforced to restrict access to diagnostic interfaces only to trusted internal systems and personnel. Employing multi-factor authentication (MFA) for administrative or diagnostic access can further reduce risk. Monitoring and logging access to diagnostic screens should be enhanced to detect anomalous or unauthorized attempts promptly. Organizations should conduct thorough security assessments of the RBI platform deployment, including penetration testing focused on authentication bypass scenarios. Until a vendor patch is available, consider deploying web application firewalls (WAFs) with rules to detect and block suspicious requests targeting the diagnostic interface. Training and awareness for IT and security teams on this vulnerability and its exploitation methods will improve incident response readiness. Finally, organizations should engage with RBI for timely updates and patches addressing this vulnerability.

Description

The Restaurant Brands International (RBI) assistant platform through 2025-09-06 relies on client-side authentication for use of the diagnostic screen.

Impact

For European organizations using the RBI assistant platform, this vulnerability poses a significant risk to operational security and data confidentiality. The diagnostic screen likely contains sensitive information about system health, configurations, or operational metrics, which if accessed by unauthorized parties, could facilitate further attacks or disrupt services. The integrity impact means attackers might alter diagnostic data or configurations, potentially causing misdiagnosis or operational failures. Availability impact, although low, could still lead to denial of diagnostic services, complicating incident response or maintenance. Given the network-based attack vector and no requirement for privileges or user interaction, exploitation could be automated and widespread if the platform is exposed externally or insufficiently segmented internally. European food service providers or franchisees relying on RBI’s platform may face operational disruptions, reputational damage, and regulatory scrutiny, especially under GDPR if personal or operational data is compromised. The vulnerability also raises concerns about supply chain security in the food service sector, which is critical for public health and economic stability.

CWE-603Use of Client-Side Authentication (opens in a new tab)
Base weakness
A client/server product performs authentication within client code but not in server code, allowing server-side authentication to be bypassed via a modified client that omits the authentication check.
Architecture and Design
Do not rely on client side data. Always perform server side authentication.
