orval before 8.29.0 fails to escape OpenAPI media-type keys when emitting them into single-quoted Content-Type string literals in generated code. Attackers can inject JavaScript through crafted media-type keys in OpenAPI specifications that executes when generated fetch operations or mock resolvers are invoked.
