CVE-2026-40293 is a medium-severity security vulnerability in github.com/openfga/openfga (go), affecting versions >= 0.1.4, <= 1.13.1. It is fixed in 1.14.0.
Description When OpenFGA is configured to use preshared-key authentication with the built-in playground enabled, the local server includes the preshared API key in the HTML response of the /playground endpoint. The /playground endpoint is enabled by default and does not require authentication. It is intended for local development and debugging and is not designed to be exposed to production environments. Am I Affected? You are affected if you meet each of the following preconditions: You are running OpenFGA with --authn-method preshared, and The playground is enabled, and The playground endpoint is accessible beyond localhost or trusted networks. Fix Upgrade to OpenFGA v1.14.0, or disable the playground by running ./openfga run --playground-enabled=false.
CVE-2026-40293 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no 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 (>= 0.1.4, <= 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.

CVE-2026-40293 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
github.com/openfga/openfga (go) versions >= 0.1.4, <= 1.13.1 is affected.
Yes. CVE-2026-40293 is fixed in 1.14.0. Upgrade to this version or later.
Whether CVE-2026-40293 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

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.
