CVE-2025-15548

Adjacent traffic disclosure via unencrypted web endpoints

Published Jan 29, 2026 · Updated Jan 29, 2026

Missing encryption in TP-Link Systems Inc. VX800v v1.0 endpoints allows attackers to intercept sensitive HTTP traffic. The affected endpoints transmit sensitive values over HTTP without the application-layer encryption used elsewhere in the web interface. Exploitation requires access to an adjacent network segment and no authentication, and it compromises only the confidentiality of transmitted data.
