CVE-2026-108161 Details
Description
FusionPBX through 5.6.5 contains an OS command injection vulnerability in call_recordings::download() that allows unauthenticated attackers to execute commands by placing calls with malicious caller ID values. When the record_name filename template is enabled, attackers can embed shell metacharacters like $(...) in the Caller-ID name or number, executing commands as the web server user once a privileged user downloads multiple recordings as a ZIP.
An OS command injection vulnerability has been identified in FusionPBX versions through 5.6.5. The issue resides in the call_recordings::download() function, where unauthenticated attackers can execute commands by manipulating caller ID values. When the record_name filename template is active, attackers can insert shell metacharacters, such as $(...), into the Caller-ID name or number. This exploitation allows command execution as the web server user, particularly when a privileged user downloads multiple recordings as a ZIP file.
Users can update to FusionPBX version 5.6.6 or later, where this vulnerability has been addressed.
