DescriptionNVD

The Restaurant Brands International (RBI) assistant platform through 2025-09-06 allows remote attackers to review the stored audio of conversations between associates and Drive Thru customers.

AnalysisAI

Stored audio of Drive Thru conversations between associates and customers on the Restaurant Brands International (RBI) assistant platform can be retrieved by low-privileged remote users, exposing customer and employee voice data. The platform - associated with RBI's Burger King, Tim Hortons and Popeyes brands - is affected in builds through 2025-09-06, and exploitation requires only an authenticated session at a low privilege level (CVSS 3.1 base 7.7, AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N). Publicly available exploit code exists and the issue has been covered in public reporting, though it is not confirmed actively exploited (CISA KEV); risk is elevated by the changed-scope, high-confidentiality impact and by the fact that only parties able to reach and authenticate to this proprietary platform are affected.

Technical ContextAI

The root cause class is CWE-669, Incorrect Resource Transfer Between Spheres: the assistant platform moves stored conversation audio (a resource belonging to the sphere of customers and Drive Thru associates) into a context reachable by a lower-privileged platform user, rather than enforcing an access boundary around the retained audio store. The CVSS vector's Scope:Changed (S:C) and Confidentiality:High (C:H) with zero Integrity/Availability impact is the textbook signature of this class - the sensitive data crosses a trust boundary that the vulnerable component was never intended to bridge, so the impact lands on parties outside the component being attacked. Relevant CPE data (cpe:2.3:a:rbi:restaurant_brands_international_assistant:*:*:*:*:*:*:*:*) marks the whole product line as affected with no version granularity, suggesting the audio-retention/playback design rather than a single injected defect is at fault; the 'through 2025-09-06' boundary appears to be a disclosure/reporting cutoff date rather than a confirmed patched release. The attack surface is the platform's network-reachable audio review functionality, which processes and serves recordings captured in drive-thru order-taking workflows.

RemediationAI

No vendor-released patch identified at time of analysis; the CPE wildcard version and the absence of any fix reference in the available intelligence mean no exact patched version can be cited, so remediation must be compensating-control driven until RBI publishes an advisory. The highest-value action is to eliminate or sharply shrink the exposed resource: purge stored drive-thru conversation audio on a short retention schedule (or disable audio retention entirely) so that a low-privileged account has no historical recordings to retrieve - the trade-off is loss of QA, dispute-resolution and training recordings, and any legal-hold or consent obligations must be checked first. Second, enforce least privilege on the assistant platform: audit and reduce accounts holding the platform privilege level that satisfies PR:L, remove shared or stale service accounts, require MFA on every interactive login, and segregate the audio-review function so that only a small named group can reach it - this can slow operations and add friction for store supervisors. Third, apply network segmentation and rate/anomaly monitoring on the endpoints that serve audio playback, alerting on bulk retrieval or off-hours access patterns; this is detection rather than prevention and will generate false positives for legitimate supervisors. Because publicly available exploit code exists, treat any unpatched, internet-reachable deployment of the RBI assistant platform as exposed and prioritize restricting external reachability to it while awaiting an RBI patch or advisory; once a vendor fix ships, deploy it immediately and rotate any credentials used by accounts that could have exercised the flaw.
