Overview

GCDWebServer is a modern and lightweight GCD based HTTP 1.1 server designed to be embedded in iOS, macOS & tvOS apps.

Affected versions of this package are vulnerable to Information Exposure. An issue was discovered in GCDWebServer before 3.5.3. The method moveItem in the GCDWebUploader class checks the FileExtension of newAbsolutePath but not oldAbsolutePath. By leveraging this vulnerability, an adversary can make an inaccessible file be available (the credential of the app, for instance).
