CVE-2026-9587: Sangoma Switchvox SMB Edition

High severity, CVSS 7.1. EPSS: 0.4% chance of exploitation in the next 30 days.

An authenticated local file inclusion vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The play_file functionality accepts user-controlled input through the sound_path parameter and fails to properly validate file paths before accessing the underlying filesystem. By supplying absolute paths, an authenticated attacker can retrieve files outside the intended directory scope.
