EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3% (24th percentile of EPSS-scored CVEs). 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).

No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

The SafeLine SL6 and SL6+ devices integrated into elevator emergency intercom systems are vulnerable to an authentication bypass. This vulnerability allows attackers to bypass authentication requirements and access the device's configuration service via the Bluetooth Low Energy (BLE) interface. Consequently, an attacker within wireless range can gain unauthorized administrative access to the device configuration.
