CVE-2025-30239

Stored credential disclosure via hard-coded firmware keys

Published Aug 10, 2026 · Updated Aug 10, 2026

Hard-coded keys in TP-Link Aginet device firmware allow attackers with storage access to decrypt sensitive configuration data. The firmware embeds the cryptographic keys used to protect stored configuration, allowing the recovered keys to decrypt credentials and service-related information. Exploitation requires access to device storage; no network-only path or service interruption is reported.
