Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

Overview

Some end users of OpenFGA v1.5.0 or later are vulnerable to authorization bypass when calling Check or ListObjects APIs.

Am I Affected?

You are very likely affected if your model involves exclusion (e.g. a but not b) or intersection (e.g. a and b) and you have any cyclical relationships. If you are using these, please update as soon as possible.

Fix

Update to v1.5.3

Backward Compatibility

This update is backward compatible.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/openfga/openfga, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/openfga/openfga to 1.5.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-31452 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
