EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 56% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

An unauthenticated reflected cross-site scripting (XSS) vulnerability exists in Sangoma Switchvox SMB Edition version 8.3 (104997). The application fails to properly sanitize the portal parameter supplied to the invalid_browser and invalid_browser_login handlers. User-supplied data is reflected into JavaScript generated by the application, allowing attacker-controlled script execution within a victim's browser.
