CVE-2026-44239: FreePBX: Authenticated Local File Inclusion in Dashboard Module

FreePBX is an open source IP PBX. Prior to 16.0.22 and 17.0.5, the Dashboard module's getcontent AJAX handler includes PHP files based on user-supplied input without path sanitization. The $_REQUEST['rawname'] parameter is concatenated into an include() call with a .class.php suffix, allowing path traversal via ../ sequences to include arbitrary .class.php files from the filesystem. The included file's PHP code executes before the subsequent class instantiation error occurs. This vulnerability is fixed in 16.0.22 and 17.0.5.

Security readout for executives and security teams

Plain-English summary

FreePBX has a high-severity authenticated file inclusion flaw in its Dashboard module. A logged-in user could influence which PHP class file is included, causing PHP code in that file to run. This can threaten confidentiality and integrity, especially on systems with many administrative users or exposed management interfaces.

Executive priority

Prioritize remediation for internet-reachable or broadly administered FreePBX systems. The flaw needs authentication, but successful abuse can execute PHP from included class files and affect sensitive PBX management infrastructure. Patch promptly and tighten administrative exposure.

Technical view

The getcontent AJAX handler concatenates $_REQUEST['rawname'] into an include() path with a .class.php suffix and lacks path sanitization. Traversal sequences can include arbitrary .class.php files from the filesystem. The included PHP executes before the later class-instantiation failure. Fixed versions are 16.0.22 and 17.0.5.

Likely exposure

FreePBX systems running affected security-reporting/Dashboard module versions: below 16.0.22, or 17.0.1 through below 17.0.5. Exposure requires an authenticated user able to reach the vulnerable Dashboard AJAX handler.

Exploitation context

The source bundle does not show KEV listing or active exploitation evidence. Exploitation is authenticated, network-accessible, low complexity, and requires a precondition according to CVSS. Treat shared administrator accounts, weak account governance, or exposed management portals as risk amplifiers.

Researcher notes

Evidence is limited to the CVE record and GitHub advisory reference in the bundle. No CPEs are listed. The flaw is CWE-98 with CVSS 4.0 score 7.6. Do not assume arbitrary extension inclusion; the described include path appends .class.php.

Mitigation direction

  • Upgrade affected FreePBX installations to 16.0.22 or 17.0.5.
  • Review the FreePBX advisory for any additional vendor instructions.
  • Restrict FreePBX administrative access to trusted networks or VPN users.
  • Audit and remove unnecessary FreePBX accounts with Dashboard access.
  • Monitor vendor channels for follow-up fixes or guidance.

Validation and detection

  • Inventory FreePBX security-reporting/Dashboard module versions across all PBX systems.
  • Confirm patched systems report version 16.0.22, 17.0.5, or later.
  • Identify whether FreePBX admin interfaces are internet reachable.
  • Review recent authenticated access and administrative activity for anomalies.
  • Confirm no vulnerable versions remain in production, staging, or backups.
