CVE-2026-1668: Input Validation Vulnerability on Multiple Omada Switches

Noroxi assessment

Priority: Monitor (action score 30/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1% (FIRST EPSS); higher than 64.2% of all records.
  • Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
