CVE-2026-87791Network attack vector

File disclosure via unchecked upload path

Published Sep 15, 2026 · Updated Sep 15, 2026

Path traversal in Developers Italia Design Scuole Italia 2.6.0 through 2.18.1 allows remote attackers to read server files. The reserved_file_check function in functions.php appends the untrusted file query parameter to the WordPress uploads directory and passes the resulting path to file_exists and readfile without resolving it or verifying directory containment. No account is required; disclosure is limited to files readable by the web server process.
