CVE-2025-13954

Administrative access via hard-coded cryptographic keys

Published Dec 10, 2025 · Updated May 28, 2026

Authentication bypass in the EZCast Pro II Admin UI before 1.17478.177 allows attackers to gain full administrative access. The Admin UI relies on hard-coded cryptographic keys when enforcing authorization, so possession or recovery of the shared key defeats its access checks. An attacker within network reach of the dongle can access protected administration functions without valid per-device credentials.
