This makes it possible for unauthenticated attackers to view potentially sensitive information contained in the exposed file.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Developer Toolbar WordPress plugin exposes a publicly accessible phpinfo.php script that reveals detailed server configuration information including PHP version, loaded extensions, file paths, environment variables, and system details.
