DescriptionNVD

The Restaurant Brands International (RBI) assistant platform through 2025-09-06 allows remote attackers to adjust Drive Thru speaker audio volume.

AnalysisAI

The Restaurant Brands International (RBI) assistant platform, used across brands such as Burger King, Popeyes, and Tim Hortons, fails to properly authorize requests to an endpoint that controls Drive Thru speaker audio volume, allowing remote unauthenticated attackers to change that volume on affected deployments through 2025-09-06. Publicly available exploit code exists, though the flaw (CWE-863) yields only a low-integrity impact with no confidentiality or availability effect, so successful exploitation produces nuisance-level operational disruption rather than data access or control of the broader platform. EPSS sits at 0.39% (31st percentile) and the issue is not in CISA KEV, so real-world risk is driven primarily by whether a given restaurant's assistant platform endpoint is internet-reachable.

Technical ContextAI

The root cause is CWE-863 (Incorrect Authorization): an API or web endpoint exposed by the RBI assistant platform performs its volume-adjustment function without validating that the caller is permitted to do so, effectively an authentication/authorization bypass on that specific action. The CVSS v3.1 vector AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N characterizes this as network-reachable, low complexity, requiring no privileges and no user interaction; the Scope:Changed (S:C) rating reflects that the software flaw in the assistant platform influences a component outside its own security authority - the physical Drive Thru audio system - rather than any expansion of attacker control over the platform itself. The CPE cpe:2.3:a:rbi:restaurant_brands_international_assistant:*:*:*:*:*:*:*:* indicates the wildcard covers all versions of the RBI assistant platform through the 2025-09-06 cutoff, consistent with the description. Notably, the impact profile is deliberately narrow: only audio volume (I:L) is affected, with no data exposure or loss of availability.

RemediationAI

No vendor-released patch was identified at the time of analysis, and RBI has not published a corresponding advisory in the available references, so remediation must rely on compensating controls. The primary containment step is to remove internet reachability of the assistant platform's Drive Thru control endpoints - place them behind a VPN or restrict them to known management/restaurant IP ranges via firewall or reverse-proxy allowlists - which directly defeats the AV:N/PR:N exploitation path at the cost of blocking legitimate remote administration from arbitrary locations. If the remote volume-control capability is not operationally required, disable or unroute that endpoint entirely; the trade-off is the loss of remote audio-management functionality. Where the endpoint must remain reachable, add an authorization layer (session or token validation) in front of the volume-control action, though this is a custom control and not a substitute for a vendor fix. Finally, monitor assistant platform access logs for anomalous volume-change requests and treat unexpected configuration changes to Drive Thru speaker levels as indicators of exploitation. Administrators should track RBI's channel for an official patched release, as none is confirmed in the provided data.
