Last modified
CVE-2026-9586 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. An unauthenticated SQL injection vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The /pa endpoint processes XML content beginning with <PolycomIPPhone> and directly concatenates the user-controlled PhoneIP value into PostgreSQL queries without sanitization or parameterization. An unauthenticated remote attacker can execute arbitrary SQL statements against the backend PostgreSQL database using a single crafted request, including database operations and remote code execution.. CISA has confirmed active exploitation in the wild. EPSS estimates a 1.09% chance of exploitation in the next 30 days.
