CVE-2024-31452

Status: AnalyzedCritical (9.8)—

OpenFGA is a high-performance and flexible authorization/permission engine. Some end users of OpenFGA v1.5.0 or later are vulnerable to authorization bypass when calling Check or ListObjects APIs. You are very likely affected if your model involves exclusion (e.g. `a but not b`) or intersection (e.g. `a and b`). This vulnerability is fixed in v1.5.3.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
