CVE-2024-23820: Openfga

Medium severity, CVSS 6.5. EPSS: 0.7% chance of exploitation in the next 30 days.

OpenFGA, an authorization/permission engine, is vulnerable to a denial of service attack in versions prior to 1.4.3. 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. Version 1.4.3 contains a patch for this issue.

Affected products

• Openfga Openfga: before 1.4.3 (fixed in 1.4.3)
