Description
Description
In OpenFGA, when MySQL is being used as the datastore, two distinct check requests can return the same response.
Preconditions
This applies if the following preconditions are met:
- You run OpenFGA with MySQL as the datastore
- Your authorization decisions rely on case-sensitive user strings.
Fix
Upgrade to OpenFGA 1.18.0 or greater.
Acknowledgements
OpenFGA would like to thank @sahajamoth for the detailed report.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/openfga/openfga | all versions | 1.18.0 |
Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
Update github.com/openfga/openfga to 1.18.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cf98-j28v-49v6 is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-cf98-j28v-49v6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-cf98-j28v-49v6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-cf98-j28v-49v6 in your dependencies?
O3 detects GHSA-cf98-j28v-49v6 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
