Admin-level file disclosure via unrestricted read feature
Published Jul 10, 2026 · Updated Jul 10, 2026
Access bypass in Drupal Examples for Developers before 4.0.6 allows remote authenticated users to read PHP-accessible files. The file_example submodule's "Read from a file" feature accepts unrestricted file selections and returns any file readable by the PHP process. The submodule must be installed, and exploitation requires an administrator-level account; the vendor documents file exposure, while CISA scores low confidentiality and integrity impacts.
