CVE-2025-62646 Overview
CVE-2025-62646 affects the Restaurant Brands International (RBI) assistant platform through version dated 2025-09-06. The flaw allows remote attackers with low-privilege access to retrieve stored audio recordings of conversations between restaurant associates and Drive Thru customers. RBI operates Burger King, Tim Hortons, and Popeyes, meaning the exposure spans tens of thousands of locations. The issue is classified under [CWE-669: Incorrect Resource Transfer Between Spheres], indicating that data crossed an authorization boundary it should not have. Public reporting by independent researchers, including a writeup on Bob da Hacker Blog, brought the issue to RBI's attention.
Critical Impact
Authenticated attackers can access stored Drive Thru audio recordings, exposing customer voices, order details, and potentially payment information spoken aloud at thousands of quick-service restaurants.
Affected Products
- RBI Restaurant Brands International Assistant platform through 2025-09-06

Technical Details for CVE-2025-62646
Vulnerability Analysis
The RBI assistant platform records and stores Drive Thru audio between staff and customers for quality and training purposes. The platform fails to enforce proper authorization checks when serving these audio assets to authenticated users. A remote attacker holding any low-privileged account on the platform can request stored recordings outside their authorization scope. The CWE-669 mapping indicates resources were transferred across a trust boundary without revalidation. Because the impact is bounded to confidentiality of stored recordings, integrity and availability of the underlying systems are not directly affected by this specific issue.
Root Cause
The root cause is missing or incomplete access control between the API responsible for retrieving stored audio and the user identity making the request. Object identifiers for audio recordings appear to be enumerable or accessible without binding the requesting user to the originating restaurant or session. This pattern aligns with broken object-level authorization, a common failure mode in API-driven cloud platforms.
Attack Vector
The attack vector is the network. An attacker authenticates to the RBI assistant platform with a low-privileged associate or franchise-tier account, then issues requests against the audio retrieval endpoint with identifiers belonging to other restaurants or time windows. No user interaction is required. The scope is changed because data captured from customers, who are not platform users, is exposed through the application's own authorization model. See the Malwarebytes News Article and the Yahoo News Report for additional context on the exposed surface.
No verified exploit code has been published. The vulnerability is described in prose by the original researcher; no proof-of-concept payloads are required beyond authenticated API requests against the audio retrieval endpoints.
Detection Methods for CVE-2025-62646
Indicators of Compromise
- Bulk or sequential requests against RBI assistant audio retrieval endpoints from a single authenticated session
- Audio downloads associated with restaurant identifiers outside the requester's assigned location or franchise group
- Anomalous access from associate accounts during hours when those accounts are not normally active
Detection Strategies
- Audit application logs for any account retrieving recordings tied to multiple restaurant IDs in short timeframes
- Compare each audio download request's session identity against the restaurant scope bound to that identity, and alert on mismatches
- Correlate platform authentication events with downstream API calls to detect credential reuse or token replay
Monitoring Recommendations
- Forward RBI assistant access logs and API gateway telemetry to a centralized analytics platform for retention and review
- Establish baselines for normal audio-access volume per associate account and alert on deviations
- Monitor for newly created or dormant accounts suddenly retrieving stored media assets
How to Mitigate CVE-2025-62646
Immediate Actions Required
- Confirm with RBI or the platform operator that server-side authorization checks now bind every audio object to the requesting user's restaurant scope
- Rotate credentials and API tokens for all associate, manager, and integration accounts that had access to the assistant platform
- Review historical access logs from before 2025-09-06 for evidence of unauthorized audio retrieval
- Restrict associate account permissions to the minimum required for daily operations
Patch Information
No vendor advisory URL is published in the NVD record at the time of writing. RBI has not released a public patch identifier through NVD. Operators should contact RBI directly to confirm remediation status of the assistant platform and request written confirmation that authorization controls on audio retrieval endpoints have been corrected. Refer to the Archived Page and the Web Archive Blog Post for the original technical writeup.
Workarounds
- Disable or restrict access to the audio retrieval features of the RBI assistant platform until vendor confirmation of remediation
- Limit platform access to network ranges associated with managed restaurant locations using IP allow-listing where supported
- Disable accounts for terminated or transferred associates immediately rather than relying on scheduled deprovisioning
- Where audio capture is not legally required, evaluate whether Drive Thru recording can be paused pending remediation
