How severe is CVE-2024-31452?

CVE-2024-31452 has a CVSS score of 8.1/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2024-31452?

CVE-2024-31452 affects the following packages: github.com/openfga/openfga (Go). Ecosystems affected: Go.

How do I fix CVE-2024-31452?

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.

How do I detect CVE-2024-31452 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/openfga/openfga. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2024-31452 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2024-31452?

O3 pinpoints whether CVE-2024-31452 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-31452 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-31452 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-31452?

CVE-2024-31452 has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 46th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2024-31452 published, and has it been updated?

CVE-2024-31452 was published on April 16, 2024 and was last updated on April 2, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

OpenFGA is a high-performance and flexible authorization/permission engine. Some end users of OpenFGA v1.5.0 or later are vulnerable to authorization bypass when calling Check or ListObjects APIs. You are very likely affected if your model involves exclusion (e.g. a but not b) or intersection (e.g. a and b). This vulnerability is fixed in v1.5.3.
