Description
Overview
During our internal security assessment, it was discovered that OpenFGA versions v0.2.3 and prior are vulnerable to authorization bypass under certain conditions.
Am I Affected?
You are affected by this vulnerability if you are using openfga/openfga version v0.2.3 or prior, and your model has a relation defined as a tupleset (the right hand side of a ‘from’ statement) that involves anything other than a direct relationship (e.g. ‘as self’)
How to fix that?
Upgrade to version v0.2.4.
Backward Compatibility
This update is not backward compatible. Any model involving rewritten tupleset relations will no longer be acceptable and has to be modified.

Open-source dependencyDetect
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.
Fix
Update github.com/openfga/openfga to 0.2.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39342 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.
