Packages

| Go | github.com/openfga/openfga | < 0.2.4 | 0.2.4 |
Details
As written in the advisory (Markdown source, shown as plain text).
### 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` and you added a tuple with a wildcard (*) assigned to a tupleset relation (the right hand side of a ‘from’ statement).
### How to fix that?
Upgrade to version `v0.2.4`.
### Backward Compatibility
This update is not backward compatible with any authorization model that uses wildcard on a tupleset relation.
