Threats affecting pkg:github/freepbx/framework

CVE-2026-73661 is a high-severity vulnerability in the FreePBX Framework module that allows an authenticated user with backup-restore or write access to crafted backup files to disable authentication during restoration. This occurs because the restore process permits restoring the hidden AUTHTYPE setting with the value 'none', bypassing the user interface's removal of this insecure setting. The issue affects FreePBX versions prior to 16.0.47 and 17.0.30 and is fixed in these versions.

CVE-2026-72578 is a high-severity cross-site request forgery (CSRF) vulnerability in FreePBX Framework version 17.0. It allows an unauthenticated remote attacker to perform administrative actions by exploiting the privileges of an authenticated administrator. The vulnerability has a CVSS score of 8.8, indicating a significant risk to confidentiality, integrity, and availability. No official patch or remediation guidance has been provided yet.

FreePBX is an open-source web-based graphical user interface (GUI) that manages Asterisk. Prior to versions 16.0.45 and 17.0.24 of the FreePBX framework, an authenticated local privilege escalation exists in the deprecated FreePBX startup script `amportal`. In the deprecated `amportal` utility, the lookup for the `freepbx_engine` file occurs in `/etc/asterisk/` directories. Typically, these are configured by FreePBX as writable by the **asterisk** user and any members of the **asterisk** group. This means that a member of the **asterisk** group can add their own `freepbx_engine` file in `/etc/asterisk/` and upon `amportal` executing, it would exec that file with root permissions (even though the file was created and placed by a non-root user). Version 16.0.45 and 17.0.24 contain a fix for the issue. Other mitigation strategies are also available. Confirm only trusted local OS system users are members of the `asterisk` group. Look for suspicious files in the `/etc/asterisk/` directory (via Admin -> Config Edit in the GUI, or via CLI). Double-check that `live_dangerously = no` is set (or unconfigured, as the default is **no**) in `/etc/asterisk/asterisk.conf` file. Eliminate any unsafe custom use of Asterisk dial plan applications and functions that potentially can manipulate the file system, e.g., System(), FILE(), etc.

FreePBX Endpoint Manager is a module for managing telephony endpoints in FreePBX systems. Versions are vulnerable to authentication bypass when the authentication type is set to "webserver." When providing an Authorization header with an arbitrary value, a session is associated with the target user regardless of valid credentials. This issue is fixed in versions 16.0.44 and 17.0.23.
