CVE-2026-1668: Tp-link omada sg2005p-pd firmware improper input validation vulnerability

Tp Link · Omada Sg2005p Pd Firmware

The web interface on multiple Omada switches does not adequately validate certain external inputs, which may lead to out-of-bound memory access when processing crafted requests. Under specific conditions, this flaw may result in unintended command execution.<br>An unauthenticated attacker with network access to the affected interface may cause memory corruption, service instability, or information disclosure. Successful exploitation may allow remote code execution or denial-of-service.
