Which packages are affected by CVE-2026-24851?

CVE-2026-24851 affects the following packages: github.com/openfga/openfga (Go). Ecosystems affected: Go.

How do I fix CVE-2026-24851?

Update github.com/openfga/openfga to 1.11.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-24851 is resolved across your whole dependency graph.

How do I detect CVE-2026-24851 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-2026-24851 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-2026-24851?

O3 pinpoints whether CVE-2026-24851 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-2026-24851 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-24851 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-2026-24851?

CVE-2026-24851 has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 22th 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.

What type of vulnerability is CVE-2026-24851?

CVE-2026-24851 is classified as CWE-863 (CWE-863). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-24851 published, and has it been updated?

CVE-2026-24851 was published on February 6, 2026 and was last updated on April 10, 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 built for developers and inspired by Google Zanzibar. OpenFGA v1.8.5 to v1.11.2 ( openfga-0.2.22<= Helm chart <= openfga-0.2.51, v.1.8.5 <= docker <= v.1.11.2) are vulnerable to improper policy enforcement when certain Check calls are executed. The vulnerability requires a model that has a a relation directly assignable by a type bound public access and assignable by type bound non-public access, a tuple assigned for the relation that is a type bound public access, a tuple assigned for the same object with the same relation that is not type bound public access, and a tuple assigned for a different object that has an object ID lexicographically larger with the same user and relation which is not type bound public access. This vulnerability is fixed in v1.11.3.
