CVE-2026-9586Known exploitationNetwork attack vector

Unauthenticated RCE via unsanitized PhoneIP SQL query

Published Jul 17, 2026 · Updated Jul 17, 2026

SQL injection in Sangoma Switchvox SMB Edition 8.3 (104997) allows remote attackers to execute arbitrary SQL through a crafted request. The unauthenticated /pa endpoint parses XML with a PolycomIPPhone root element and inserts the user-controlled PhoneIP value directly into PostgreSQL queries. A single network request requires no credentials or user interaction and grants database read and write access plus remote code execution on the PBX.
