OpenFGA denial of service

Moderate severity GitHub Reviewed Published Jan 26, 2024 in openfga/openfga • Updated Feb 1, 2024

Package

gomod github.com/openfga/openfga (Go)

Affected versions

< 1.4.3

Patched versions

1.4.3

Description

Overview

OpenFGA is vulnerable to a DoS attack. In some scenarios that depend on the model and tuples used, a call to ListObjects may not release memory properly. So when a sufficiently high number of those calls are executed, the OpenFGA server can create an "out of memory" error and terminate.

Fix

Upgrade to v1.4.3. This upgrade is backwards compatible.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
