Multiple critical vulnerabilities have been identified in FreePBX modules, including unauthenticated remote code execution (RCE) in the UCP module, unauthenticated SQL injection in the missedcall module leading to administrator takeover, authenticated command injection in the TTS module, and authenticated RCE in the music module. These flaws affect specific versions of these modules across FreePBX 16 and 17, allowing attackers to execute arbitrary commands, bypass authentication, and gain administrative control.

FreePBX has released security advisories to address critical vulnerabilities in its API and Backup modules, affecting FreePBX API (versions prior to 17.0.9) and FreePBX Backup (versions prior to 17.0.11), which include authenticated command injection and arbitrary SSH key injection leading to remote code execution and unauthorized access.

A critical vulnerability, CVE-2026-46376, exists in FreePBX due to the use of hard-coded credentials in the User Control Panel (UCP) generic template setup process, allowing an unauthenticated, remote attacker to gain unauthorized access to user accounts and manipulate user settings if default template credentials are not immediately changed by the administrator after enabling UCP.

FreePBX released security advisories addressing authenticated SQL injection and local file inclusion vulnerabilities in the Security-Reporting cdr and dashboard modules for FreePBX 16 and 17.

FreePBX Security-Reporting userman versions 16.0.45 and prior (FreePBX 16) and 17.0.7 and prior (FreePBX 17) contain a critical vulnerability due to unauthenticated use of hard-coded credentials in the UCP interface, potentially allowing unauthorized access.

FreePBX api module version 17.0.8 and prior contain a command injection vulnerability in the initiateGqlAPIProcess() function, allowing authenticated users to execute arbitrary commands via crafted GraphQL mutations.
