- CWE-799 - Improper Control of Interaction Frequency
Summary
OpenBao before 2.6.4 and 2.7.x before 2.7.1 contains a flaw in its rate limit quota subsystem where role resolution fails for requests with form-encoded bodies or forwarded certificates, so quota rules scoped to backend-specific roles are not enforced. Valid callers can repeatedly issue tokens without consuming the configured role-based rate limit budget.
