Status: ModifiedMedium (6.5)—

In Bluetooth mesh implementation If provisionee has a public key that is sent OOB then during provisioning it can be sent back and will be accepted by provisionee.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
