Last modified

CVE-2026-1668 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. 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. EPSS estimates a 0.97% chance of exploitation in the next 30 days.

Description

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.
