Deeper analysis
CVE-2025-62645 is a critical vulnerability in the Restaurant Brands International (RBI) assistant platform through version 2025-09-06. It enables a remote authenticated attacker to obtain a token granting administrative privileges across the entire platform via the createToken GraphQL mutation. The issue, published on 2025-10-17, carries a CVSS v3.1 base score of 9.9 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) and maps to CWE-266 (Incorrect Privilege Assignment).
A remote attacker with low-privilege authenticated access can exploit the vulnerability with low attack complexity and no user interaction. Exploitation yields a token with full administrative privileges, allowing comprehensive control over the platform and resulting in high impacts to confidentiality, integrity, and availability due to the expanded scope.

Mitigating Controls (NIST 800-53 r5) AI
AC-6 enforces least privilege, directly preventing low-privilege authenticated users from obtaining administrative tokens via the createToken GraphQL mutation as described in this incorrect privilege assignment vulnerability.
AC-3 requires enforcement of approved authorizations, addressing the failure of the createToken mutation to restrict administrative token issuance to authorized users only.
AC-2 manages accounts and privileges, helping mitigate by ensuring proper assignment and monitoring of token-related access rights to prevent escalation exploits.
