The vulnerability, identified as OpenFGA Improper Policy Enforcement, allows an attacker to bypass defined access controls when certain Check calls are executed. The flaw is due to a model that defines relations with both public and non\u2011public bindings and tuples that assign different permission levels. By crafting such a model, an attacker can obtain access to resources they should not be able to. This is an access control weakness (CWE\u20111220 and CWE\u2011863) that can lead to unauthorized read or modify operations.", "risk_and_exploitability": "The CVSS base score is 5.8, indicating medium severity. The EPSS score is reported to be less than 1 percent, suggesting a very low exploitation probability at the time of analysis. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires the attacker to execute Check calls with a specifically crafted policy model and tuples, implying that the attack vector is limited to environments where the attacker can influence or create policy definitions. Because it does not require remote code execution, the risk is mainly confined to unauthorized privilege escalation within an OpenFGA deployment."}}}}, "created": "2026-02-09T10:49:39.868538+00:00", "updated": "2026-04-17T22:45:29.934465+00:00", "vendors": ["openfga", "openfga$PRODUCT$openfga"]}
