Description

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.

Weakness classification

  • CWE-401: Missing Release of Memory after Effective Lifetime
  • CWE-770: Allocation of Resources Without Limits or Throttling
