CVE-2026-44239Network attack vector

Authenticated command execution via unsanitized PHP include

Published May 29, 2026 · Updated May 29, 2026

Local file inclusion in FreePBX Dashboard 16 before 16.0.22 and 17 before 17.0.5 allows remote authenticated users to execute commands. The getcontent AJAX handler appends .class.php to the rawname request value and passes the unsanitized path to include(), so ../ sequences select and execute filesystem PHP files. Authentication with a known username is required, and execution runs as the webserver user, typically asterisk.
