CVE-2026-1668

Unauthenticated code execution via crafted web requests

Published Mar 13, 2026 · Updated Mar 13, 2026

Improper input validation in TP-Link Omada switch web interfaces allows remote attackers on the adjacent network to execute code. The interfaces process crafted external inputs without adequate validation, causing out-of-bounds memory access and, under specific conditions, unintended command execution. Network access to an affected management interface is required; exploitation can disclose information, corrupt memory, or interrupt the service.
