CVE-2026-78552
The field is interpolated directly into the nginx server block without inspection, resulting in execution of injected directives.
Does this matter?
Lower severity and a low EPSS score (0.39%). Track it; it rarely justifies an emergency change on its own.
Description
The Okta Access Gateway does not apply its Lua directive restriction to the application-level custom configuration field. The field is interpolated directly into the nginx server block without inspection, resulting in execution of injected directives.
