CVE-2026-34972 is a medium-severity incorrect authorization vulnerability in github.com/openfga/openfga (go), affecting versions >= 1.8.0, <= 1.13.1. It is fixed in 1.14.0.
Description In OpenFGA, under specific conditions, BatchCheck calls with multiple checks sent for the same object, relation, and user combination can result in improper policy enforcement. Am I affected? You are affected if you meet the following preconditions: You execute BatchCheck operations which rely on context. Multiple checks are sent within a single BatchCheck operation for the same user/object/relation combination, each containing context. The contexts between those checks differ in a specific way Fix Upgrade to OpenFGA v1.14.0 Acknowledgement OpenFGA would like to thank @bugbunny-research for the discovery and detailed report.
The application does not correctly enforce access controls, allowing a principal to access resources or operations beyond their granted permissions. Typical impact: unauthorized data access or execution of privileged operations.
CVE-2026-34972 has a CVSS score of 5.0 (Medium). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (1.14.0). Upgrading removes the vulnerable code path.

github.com/openfga/openfga (>= 1.8.0, <= 1.13.1)github.com/openfga/openfga → 1.14.0 (go)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
