Which packages are affected by CVE-2025-48371?

CVE-2025-48371 affects the following packages: github.com/openfga/openfga (Go). Ecosystems affected: Go.

How do I fix CVE-2025-48371?

Update github.com/openfga/openfga to 1.8.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-48371 is resolved across your whole dependency graph.

How do I detect CVE-2025-48371 in my Go dependencies?

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.

How do I mitigate CVE-2025-48371 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-2025-48371?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-48371 can be triaged on real exposure rather than presence alone.

Is CVE-2025-48371 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-48371 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-2025-48371?

CVE-2025-48371 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 41th 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-2025-48371?

CVE-2025-48371 is classified as CWE-285 (CWE-285). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-48371 published, and has it been updated?

CVE-2025-48371 was published on May 22, 2025 and was last updated on August 12, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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

OpenFGA is an authorization/permission engine. OpenFGA versions 1.8.0 through 1.8.12 (corresponding to Helm chart openfga-0.2.16 through openfga-0.2.30 and docker 1.8.0 through 1.8.12) are vulnerable to authorization bypass when certain Check and ListObject calls are executed. Users are affected under four specific conditions: First, calling Check API or ListObjects with an authorization model that has a relationship directly assignable by both type bound public access and userset; second, there are check or list object queries with contextual tuples for the relationship that can be directly assignable by both type bound public access and userset; third, those contextual tuples’s user field is an userset; and finally, type bound public access tuples are not assigned to the relationship. Users should upgrade to version 1.8.13 to receive a patch. The upgrade is backwards compatible.
